63 Cab On A 72 Frame

[allytle]

I've read a bunch on this and it seems pretty straightforward but I still thought I'd ask for input. I have a 63 C20 and I want to put the cab on a 72 C30 frame. It's the 157" wheelbase frame. I'm doing a flat bed so that's not an issue. I've read the radiator mounts will need to be modified and possibly move the front cab mounts. The 72 is an 8" frame though where the 63 is 6". I'm assuming that's going to make the cab sit higher. I want to lower the front end eventually.

Any tips, suggestions, or thought?
