F46,

It does require a rear end swap, but you only need to weld on new spring perches. I looked at an S-10 swap as another project. That seems like a lot of work too.

My someday plan is to pickup another 41-46 frame and do another with swapped rear, MII or Dakota and a small block or 4200 Inline 6...

But that is more than a few years off...
