1977 620 King Cab - Georgia Truck

These may be the lug nuts you need for those wheels.
 There also is an OEM replacement for the KC cab light.
You will have to cut a notch in the original mount and with the harness clip
you can plug it into your KC harness with no butchering.
More light !

I had some KC dome lenses 3-D printed, but I am going with 
the other dome light when she goes back together.
I have had my 79 since 87, she was only 8 yrs old..........

Those look like the lugs for the Toyota. The issue I had with the Chevy rims was that I wasn't getting a solid metal to metal contact due to the center hole not being large enough. Spacers helped.

I will definitely check those out. The wiring for the light was pulled by a previous owner, so I have to rewire it anyway.

Another 4x4 620, awesome! 😄

That definitely looks very interesting!! To fit the Datsun cab onto the Toyota frame probably will take a bit of fab work, but it will look and run good when finished.

I hate to say it ...but if you scrap that 620 A/C unit.....you are really fucking up.
People in Thailand & Hawaii will pay big bucks for that shit.
I sold a complete unit for a guy and the buyer in Hawaii paid 1K
for the setup. I wish I had never scrapped
 mine, and kept all of the smog parts I deleted, but that was 33 yrs ago.

 I was not aware of this, but after a quick search, my frame should not be affected. This was an issue with the previous gens' design which would cause the balljoint to fall out from the bottom. This gen has a new fail safe design where even if the balljoint fails, it will stay in. I will grab some pics when I get home from work tomorrow.

 

 

As you can see above, the lower A-arm pushes down onto the ball joint. If the ball joint fails, the A-arm wont just fall down. This was a design change after the 2005 model year. Apparently, it was implemented across all of Toyota's trucks.

I still have what's left of the A/C parts. There is not a complete system, and I am not sure if what is left is operational. Honestly, it would be cheaper to go with an aftermarket system like Vintage Air versus trying to rebuild this system. I would also run a lot better, and probably fit a lot tighter, as well. Unless you are looking for something "period" to put into your car or truck.

[Goemon]

Yeah, previous ones used the ball joints upside down

 

[Goemon]

Oh, that is the upside down lower......

Picked up some matching wheels and tires for the frame today, sans valve stems. I thought about installing the valve stems myself, but I am glad I dropped 20 bucks and had a tire shop do it instead. Got them filled and balanced as well. It took them a bit to get the beads set, and I can only imagine the frustration I would have gone through without the proper equipment.

 

They were off of a 2016 4Runner. The owner swapped to some wheels that were designed to better shed mud. His rig was immaculately clean...

 

Side view installed. They look pretty good. You can get a good sense of how big the frame is.

 

 

As you can see, the wheelbases between the two trucks are nearly identical. The axles line up pretty well.

 

 

The 620 King Cab has a 109.6" wheelbase. The 4th gen 4Runner has a 109.8" wheelbase.

 

 

The frame alone is about the length of the entire truck. Front:

 

 

Back:

 

 

The 4Runner frame is quite a bit wider than the truck.

 

 

You can't really get a sense of that until you see the body on it (it's a photochop, don't get too excited!).

 

 

This is how I am imagining it will look when "done" for now.

On the earlier dealer installed AC set ups, we use the original dealer installed underdash units, but everything else under the hood is simply NEW universal fit parts (all the dealer installed kits used universal parts under the hood anyway!), with custom made hoses to suit where YOU want them to pass thru the firewall.  We use a NEW late model Sanden compressor (MUCH more efficient & lighter than the original huge York monstrosity's!), with relatively simple spacer adaptors to mount it to the original dealer installed bracket on the engine.  Depending on the crank pulley, sometimes you need to modify the tensioner pulley bracket to line the belt up.  We have done 240Z's & a 510 this way........same should apply to the 620!
