Ok.. I think I'm getting a better understanding now. I've been looking up measuring axles and the different variables and stuff.

Ok so my c10 has factory rims and stock size tires, 5 lug. They have half moon hub caps and I feel they would look good on the 3100, kinda factory looking. I'd like to use these if possible.

I didn't pull off the tires but I did a quick measure from the tires and yes the c10 is a good 4 inches wider. So maybe a tight fit.

So I need to find a rearend...i am going back out to the guys house where I got my 3100, pickup a few things. He has a lot of old cars and I saw a bunch of rear ends by themselves. Tomorrow I'll measure the WMS of the stock axle...keep drums on right? Measure surface to surface.. I'll let you know measurement.

By Sunday I hope to get out there and find something...he doesn't have any Fords, looked like a lot of chevys, anything in particular I should look for? With available parts? He has a bunch of 50s 60s cars...

ALSO...if I'm switching to an automatic... I'd like to maybe find a steering column that will mount the same or at least look stockish... any early chevy columns I should look for? I currently have the column with the manual trans shifter.
