what body styles will work?
 

i have a 1972 lwb, 4x4, chev p/u rolling chassis. What range of years of bodys will bolt right up to existing body mount brackets and will a 2wd body fit on the frame?

Cabs should be the same, from 67-72. You'll have to use the bed that fits your frame. I think the only real difference you'll find between 2WD and 4WD cabs is the hump on the floor. I believe that 4WD cabs have the taller hump. Some 2WD cabs do, too.

A two wheel body might fit, but you have to fabricate a 4x4 center hump into the floor. Because the 4x4's transfer case.

a two wheel drive with a standard transmission would work, because the standard cabs have high humps in both 2 and 4 wd models

My cab has a low hump and came with a standard tranny. The shifter was on the tree, are they different?

Low hump 3 on the tree here also

3 speed cabs are low hump, TH400 cabs are high hump, 4 speed cabs are high hump, 4x4 cabs are high hump, auto cabs are low hump

i have a bed from a 2wd coil truck on my K20, so those interchange, and the front clips all interchange, and the cabs do other then slight differences but they will bolt up

Blue...not so on the TH400 cabs...they would be low hump if in a 2 wheel drive with a small block.

The only thing you may have to worry about, would be the possability of nooeding to cut out the low hump, and installing a high hump, and if the cab came from a 2 wheel drive 1/2 ton, then you'd need the other style rubber cab mounts. (1/2 ton 2 wheel drive used one style mount...all others used the other style mount.)

btw... welcome to the board!
