1977 Datsun 620 King Cab Deluxe

 カラシ “KARASHI”

 

 

First acquired April of 2009. Saw a listing on craigslist selling it for $1500 "running." After meeting with the owner at n offsite yard, he noticed the pickup was ransacked and several parts were missing. He sold it to be for $500. I was eventually able to scavenge for the missing parts and got the L20B running. Upgraded the carb years later to a 32/36 weber and drove it for several years as my daily. Crashed for the very first time in my life with it (hopefully the last), due to very dangerous spongy drum brakes and the car in front hard braking. A time after than, I blew the L20B on the freeway; oil every where. Needed it back on the road quick and so I was lucky to find a 1973 620 donor on craigslist with a L18 and swapped it over. Eventually, the L18 gave up and the 620 was parked for a couple years. I scored a good deal on a KA24DE, harness, and ecu, low miles, approximately 110,000 for $700. Also bought a 720 5 speed transmission from a ratsun member for $150. This is where my dreams and ambitions began; however, I was just a college student with a retail job selling cellphones. Graduated from college 2013; scored a decent job in 2015, and now we are here, dumping hard earned money on this project; and also into the necessary tools. The pickup's name is, "Karashi" a type of mustard in the Japanese cuisine. KA swap inspiration credited to ]2eDeYe thanks for the wealth of information!

Radiator/Core Support

 

Because the front radiator support was trashed, I removed the one from the 73 donor; the top is slightly different, but who cares, I was going to cut it up either way to fit a good radiator. Hence, the first step in this build was finding an aluminum radiator that fits with little modification. I know the efficiency of the radiator having a shroud and so the radiator MUST have one with electric fans. Found the perfect radiator for this and only needed minimal cutting of the core support.

 

Radiator: 84-87 Toyota Corolla AE86 (Manual) Overall Size: 23"x18"x2" thickness with shroud and fans, 5.5"

 

Test fitting the KA to figure out clearance and allowed me to work on fitting in the radiator

 

 

 

 

uF0Tx9Z.jpg

 

 

 

Approximately 5" space from water pump pulley to core support wall

 

FS3AiXy.jpg

 

Went to the junk yard and got a pair of these hold down brackets from an older model Toyota corolla, I grind them down to fit better with my dimensions

 

wY7JLgR.jpg

 

gLeFwV8.jpg

 

Also grabbed a pair of these bottom mounts; will have to figure out how to attach them to the bottom frame; I already have an idea how

 

hXFGj9z.jpg

 

CFqsJPQ.jpg

 

tXmR1HN.jpg

 

 

 

Notice the shroud does not sit flush; manufacturer was lazy with grinding down the welds and making it fit right; will do that myself; that should give me half an inch more clearance with the distributor and water pump pulley and the shroud will be more efficient

 

tALV1Ci.jpg

It's difficult to remove the radiator due to how close it is to the distributor; will have to cut the support, it blocks the bottom right corner of the radiator when trying to pull up

 

Front bumper brackets should fit without a problem

 

rdBW5pf.jpg

 

Shroud sitting in flush after an hour of tedious grinding of welds and cutting down the threaded tubes where the upper tabs sit; why does aluminum take forever to grind down!

1/2" clearance from the water pump pulley and 1" from the distributor connector; good enough!

Unfortunately mine is missing the fender tag so I'm not sure, even after researching there isn't much out there. Closest I could find was code #931.

In a tedious quest to find upper and lower radiator hoses. The engine side inner diameter of the hose has to be 1-3/8" (1.38") and of the radiator side 1-1/4" (1.25"). Oreilly's rep was super cool and ordered a bunch of molded hoses I though will work in some way or shape after modifying them and if I'm lucky I'll have both upper and lower tomorrow. One other option I thought about is using rubber inserts on the 1.25 radiator inlet/outlet and use one size flexible hoses then dress them up.

 

Any other ideas?

 

:confused:

Welcome
Nice truck , you can make an adapter , or get an exhaust shop to make you one any size you need .a short piece of tube about three inches long , this also helps if you need to turn one end of the hose to fit better .

Datsun 720 5 Speed transmission cleanup. Not fun, but easier than expected. Still needs a little scraping and scrubbing in some corners. Got most of the crud by scraping it dry. I then sprayed it with Purple Power degreaser and scrubbed with the wire brush, I then scrubbed and then scrubbed some more, pressure washed to clean it up, then scrubbed some more. Approximately two hours worth.

The harbor freight wire brush made the job simple.

I have an idea and I'm liking it...has anyone ever seen a 620 King Cab with the quarter windows deleted??? I've always thought the oval window makes the KC look a bit odd and they seem to be useless windows.

 

What do you all think?

Fast720 has a 720 single cab he extended, so it's like a windowless king cab. Looks fine, so i would think a 620 would to.

If going to that much body effort, also consider adding some length to the bed side so it starts even with the bottom of the cab body, then tapers up to original height at the back of the bed.

Very good observation and recommendation; without fixing that taper it does make the bed look out of place.

I'm a 720 guy myself and they have the same issue. I'm planning on correcting that on my project truck...eventually. :)

BMW E30 projector headlights; low and high beams. The issue is the battery in the way of the low beam; but I have an idea that I hope will work.

Just my opinion, but with so many headlight options out there these days that don't require cutting, I just can't see using those. Your ride though and they do look cool :)

Whenever I think that I'm out of my mind for putting this much time and money into an old Datsun, all I have to do is look some of your threads to know that I'm not nearly as whack as you are.

You're going to skin a few knuckles, stand up too fast and bump your head, hunt around the floor for the nuts and bolts you dropped, invent a few new cuss words and when you're finished you'll say "That wasn't so hard after all!"

I'm a big fan of HID lighting and these will allow me to do that without blinding people.

What other headlights do you recommend though?
