Switching frames frm 2wd 3/4 to 4 wd 3/4
So I just bought another truck and I'm thinking of switching the frame to a 4wd 3/4 from a 2wd 3/4. Anybody done this before? suggestions.
The 72 chevy i picked up is a c20 auto with 402 (see pics) I'd like to go with a 350 motor and trans with np205 transfer case. Thanks, O ![]() ![]() ![]() ![]() ![]() |

The C/20 with a high hump cab is a perfect donor.They use the same cab mounts,if the originals are still good enough to reuse.It's pretty much just a matter of swapping the body onto the K-model frame.

It is easy enough to change out the low hump to a high hump. I use a plasma cutter to cut out the low hump. The high hump is used to locate the mounting holes and then weld in the weld nuts. Turns out looking like factory.
