Wheel Help please!

I have a '72 C10 LWB Cheyenne 350



It was supposed to be a number matching truck but when the front pump seal went out on the trans and I pulled the engine and trans I found that the engine was a 1970 Passenger Car 350 and the Transmission was stamped T2 signifying a THM350C as evident by having 4 check balls instead of 3. So the trans is from an 1980 or newer.

Anyway the value of this truck has been greatly diminished. I also have a '72 Cheyenne 400 which I have a '72 402 and the VIN correct TH400 for it so I am going to take the wheels and seats from the non number Cheyenne 350 and put them on the 400.

Anywho I want to run 2.5" drop spindles and 3" rear drop springs and run black/chrome 20" American Racing Torque Thrust II's...I know the lug pattern is 5 x5" anyone have an idea of appropriate back spacing? furthermore anyone have a picture of the wheels on these trucks lowered?


THANKS y'all

nice truck...sorry to hear it wasn't as advertised....

....check out the suspension section for backspacing specs but they are really only a guideline...every truck is slightly different. ( Yours I'd assume ) has the later rear so it's wider than a 67-69 rear would be so that affects the rear offset. And different spindles push the wheels out different amounts over stock....

Al's71C10 has black and polished coys and has his specs posted in his build thread.

thanks, I suppose i'll just have to pull a wheel and measure for proper backspacing....not a biggy was just looking for an easy way out

I agree it's got to be frustrating to buy a numbers matching truck and then find out that is isn't. Still its a nice lookin truck.
