GoGoGo Posted August 12, 2015 Report Share Posted August 12, 2015 Don't have the pics at the moment but installed new rubbers and still have a little shake at highway speeds. Naive question - Does the solid rubber stops go to the front of the hood and the more flexible (hollow center) go to the back? Quote Link to comment
heywier427 Posted August 12, 2015 Author Report Share Posted August 12, 2015 Maybe that's my problem! I have 4 solid ones from datsunlandsocal like these: maybe the hollow ones go towards the front to crush down and give resistance against the hood latch?or maybe use larger ones? these are from a 1st gen Camaro1st world problems...

datzenmike Posted August 12, 2015 Report Share Posted August 12, 2015 Whatever you use, they must make contact with the hood and be firm like tire rubber. It should also be pinched between the hood and the fender.... support from just the underside won't do at all. It needs to resist side to side movement. 1 Quote Link to comment
datsunfreak Posted August 13, 2015 Report Share Posted August 13, 2015 If hood pins were the only way to go, they would be installed reversed, with the pins going down into engine bay. And then it would be called a hood latch. :rofl: This style is pretty unobtrusive if you ditch the big discs... maybe use larger ones? these are from a 1st gen Camaro Those look like a good option. ever seen anyone use those on a 510?

datzenmike Posted August 13, 2015 Report Share Posted August 13, 2015 If hood pins were the only way to go, they would be installed reversed, with the pins going down into engine bay. Hidden, so no one could see them. Ever. Maybe glue another set of side bumpers closer to the front of the fenders/hood. To unlock the hood you just open it to get at the pins..... 1 Quote Link to comment
Cardinal Grammeter Posted November 24, 2015 Report Share Posted November 24, 2015 I would run without a hood before I would ruin my Datsun with hood pins. There are lots of rubber suggestions above for fixing this. AGREED! and I have the thankless suck task of de-hood pinning mine which will be interesting because the only thing holding the hood is the center late - NO bumpers anywhere. Trying to think of a way to put a threaded, adjustable bumper - maybe something as small as the "head of a bolt" that catches the side edge of the hood... "Rubber headed jack bolt?" Oh I've got it (haha). Spray release agent on the hood, fender, and inners and put a Big Blop of 2-part curing silicone rubber every where you want a bumper. When dry, take the glop out and cut out the center(s) which would be perfectly shaped bumpers. Not so sure how to attach... Or maybe be sure the Blop goes into the holes and slots, don't use release agent on fenders and inners - instead mask off where you plan to cut away. Quote Link to comment
heywier427 Posted November 24, 2015 Author Report Share Posted November 24, 2015 To unlock the hood you just open it to get at the pins..... So silly... This is the best random internet pic i could find. Ive done this a few times to mk1 vw's. Paint the pin clips black, and youd never see em. This is done because a space is tight, and being able to raise the intercooler up 2-3" (by getting rid of the stock center latch) makes room for the oil cooler, ect... Not so much for the car below, but you get the point... Quote Link to comment
datzenmike Posted November 24, 2015 Report Share Posted November 24, 2015 Hey I would be proud to drive around with that on my Datsun. The point is they are not needed because the factory installed a safety latch. How many hoods have you seen blow off while driving? If you know someone who knew someone who heard of one flying off while driving then they had had a previous accident or through neglect, abuse or stupidity didn't or couldn't latch it properly. Like forgetting to tighten the lug nuts. Quote Link to comment
Trophy24 Posted November 27, 2015 Report Share Posted November 27, 2015 Even hood pins can be a fail if you forget to put the pins in. Saw that happen at Laguna Seca at one of the Shelby Club track days. A very bad day for sure Quote Link to comment
russaroll Posted November 28, 2015 Report Share Posted November 28, 2015 i was getting the wobble so i found another hood and stuck some aeroCatch pins on Quote Link to comment
carterb Posted November 29, 2015 Report Share Posted November 29, 2015 My 72 Bluebird DX has adjustable bumpers. I don't know if they are factory or not but they certainly do the trick. 1 Quote Link to comment

datzenmike Posted November 29, 2015 Report Share Posted November 29, 2015 My '70 Dart had those. Most Chryslers used to. Quote Link to comment

Cardinal Grammeter Posted June 4, 2016 Report Share Posted June 4, 2016 Update: Yeah, took out my hood pins, soldered up the holes. Nice fine hood. Hood flies open on highway few months later. Is that Irony? Started a repair/diagnosis thread with pics on it. Quote Link to comment
Draker Posted June 4, 2016 Report Share Posted June 4, 2016 I saw your thread... bummer. Quote Link to comment
heywier427 Posted June 4, 2016 Author Report Share Posted June 4, 2016 Hood pins for the win? I added rubber weather striping on top of my front fender bumpers to build them up a bit. Adjusted the hood latch a bit tighter too. Now it only wiggles instead of looking like jello. But now only at speeds over 100 :) Quote Link to comment

datzenmike Posted June 4, 2016 Report Share Posted June 4, 2016 Hoods don't normally fly off. Not the hoods fault if they do, it's the owner. Hood pins to hold the hood on is the same as welding your rims on to keep them from falling off. Proper lugs and torque is less drastic. That notch isn't from opening and closing. It's from chafing because the latch was loosely fitted. Probably the hood shaking and not secured. 1 Quote Link to comment
tr8er Posted June 4, 2016 Report Share Posted June 4, 2016 Shit. My windshield doesn't even have a factory safety latch... I'm going to install windshield pins. 1 Quote Link to comment

I agree, everything needs to be accordingly, I've been driving big rigs for over 18 years now and you would not believe the kind of damage loose things create by simply rubbing against other things from simple vibration.

Cardinal Grammeter Posted June 15, 2016 Report Share Posted June 15, 2016 I'll say it again, the latch is aligned properly. The torsional hood flap is the cause. However, there is another possible problem: The post popup spring was so weak it could not pop the hook up - I had to install an inner spring. The hood now pops up without issue, however, this spring is what keeps the post loaded onto the latch pawl. If this spring is too weak, it is possible on a rough road or pot hole that the post could come off the pawl (inertia force of hood pushes it down.) If this happens, it would then slam into the pawl on its return up and perhaps cause the pawl to move out of the way again due to a weak pawl return spring. Quote Link to comment
Cardinal Grammeter Posted June 17, 2016 Report Share Posted June 17, 2016 QUICKIE HOOD FLAP FIX: (2) pieces of 2" long 3/4" heater hose each laid on top of the core support next to the fenders. There are no convenient holes to plastic tie them too, but a long loose string to anything nearby keeps them nearby if they fall off when opening the hood. Pretty ghetto, huh? Quote Link to comment
datzenmike Posted June 17, 2016 Report Share Posted June 17, 2016 Glue them to the under side of the hood so they are out of the way when opened. Quote Link to comment
datsuntech Posted October 2, 2017 Report Share Posted October 2, 2017 NECRO POST FYI for those who want adjustable hood stops on the rad cradle. I used Ford threaded stops. They are plentiful in the junkyard and work quite well. I remove the plastic clip and use two nuts or a threaded nut insert. http://shop.broncograveyard.com/Images/36081.jpg Quote Link to comment
