Since the car is apart I thought I might replace the bulb that I assume is in the box that provides light for the fiber optics to the dash knobs. Has any one put an LED "bulb" in to replace the stock rather dim bulb? I have not been able to find instructions on how to access the light source bulb. I did try several Ratsun searches using as many terms as I could think of. I had no luck. Does anyone know how the get to the fiber optics light source?
I did replace several of the dash lights with LED bulbs and that did improve the illumination to the gauges.
I am putting the headliner back in. I lost the baggie that I had put the fittings into. I do not find I have any screws or bolts that appear to fit correctly. To take this photo, I have temporarily held the top cross piece in place with partially screwed in crude over sized screws.
Question #1 , What type and size of attachment fittings go here (the red arrows above)?
Question #2, I don’t have a photo I took before I took the headliner out and I am a bit perplexed as to the re-assembly. From the glue marks on the metal I assume the headliner edge glues to this crosspiece AND this crosspiece then goes on top of the headliner. I just don’t remember what this looked like. Is this metal edge supposed to show? Is there an interior appearance trim piece that is supposed to cover this piece? Or are the exposed heads of the attachment fittings supposed to show?
Question #3, Is it best to re-install the headliner at the front windshield first and then work back to the rear?
I own a 1973 Datsun 610 station wagon (that was actually made in late 1972). Please see the photo below. All three sensors have almost the same dimensions (miniscule difference) but only the original sensor, that is now defective, actually fits into the threaded hole of the engine block. Does anyone know of a place to get a sensor that will fit into the engine block hole and if so, what the model number of that sensor is?
I was told on two separate occasions that the replacement sensors I purchased would fit, but they don't. The original sensor barely fits; it is almost too big to go in the hole.
But before I get to that, there are a few more little electrical mysteries. Please see the photo of the back of the instrument cluster, the items with the pink circles. I have no loose wires. Is something supposed be plugged in?
I was thinking of using wedge base LED lights in the sockets identified by bits of blue tape; anyone have any comments about this?
And then in the photo from the steering wheel side, there is a two-wired bulb in a simple plastic push-in mount. This is not a push-in and twist device. The bulb turns on whenever the headlights are turned on. Beats me what this bulb is supposed to illuminate.
Now the FOUND IT:
Awhile back I asked about where to find the sockets (several were disintegrated). Auto parts places, even Datsun parts places didn’t know where to get the sockets. Well, the sockets are not rare, they are a part common on older US cars. Here is the eBay site I bought from: retromotive (29661) on eBay.
I only bought five because I didn’t know if they would fit. They fit perfectly. I am going to replace the remaining five old ones. Just a little word of caution, some of the ones I received had a teeny bit of residual plastic flash from molding. If you don’t trim this, it can make it very hard to remove the socket if you ever need to remove the socket because the untrimmed plastic tends to wedge the socket too firmly in the circuit board.
I have included photos and a drawing I did of the socket shape with the relevant dimensions.
