Re: 1979 C10 Sport step side on air

Built in St Louis;

I see it has the LR60-15 tires with rally wheels on it originally. Those were the fattest tires you could get.

This is kind of what it would have looked like new (1980 non-Sport shown).

Thanks Keith! That's great info and a good looking truck.
LR60-15 converts to a 275/60r15 and that is what the rear is getting for sure and hopefully I can fit them on the front. I know from the spec sheet this truck is supposed to have rally's on it, but i got this set of these pa6 wheels. I always thought these were cool on the sports.

Re: 1979 C10 Sport step side on air

After picking it up and going through the cab full of parts, it got stuffed in the garage until I got the 86 going and ready for Power tour. After Power Tour I roughly threw the bed together and took off the haggard looking wheels. I also bolted a set of super clean blue doors I had on it. This gave me a better sense of what i had. Next it needed to have an altitude adjustment.

Re: 1979 C10 Sport step side on air

I found this picture of a 1979 fleetside sport that has the color combo that my truck is supposed to have. This one even has the wheels I plan on running. I need to find a set of factory bed rails now. I really wish i had the correct front pumper also, that is going to be tough to find.

Re: 1979 C10 Sport step side on air

Next was to lower it and try my PA6 wheels on it. I think it looked good. So I thought if this low was good and the ground would be great. I bought a Chassis Fab air ride kit way back when I started to put the 86 together and then decided against it on that truck. The kit was on the shelf still and this was the perfect candidate for it.

Re: 1979 C10 Sport step side on air

Last month i finally started on the front suspension. The ends of the front crossmember had to be trimmed and the brake hose boss had to be cut out and patched. There wasn't much info on the upper mount placement. I talked to other guys who installed this "kit" and got some pictures from them. I mocked it up and did a lot of measuring. When I thought it was close enough i burned it in.

Re: 1979 C10 Sport step side on air

Once it was all welded up and painted, I bolted it back together. Then I had to see what it looked like air out. I had to shorten a much better .mp4 to .gif to get it to upload but you get the idea.
