4x2 to 4x4 swap question...

[rory71]

Hey guys, I have spent way too many hours on here searching through all the awesome builds and man am I impressed, lots of great builds! I have a beat up 76 K20 that needs too much work to save, I have seen a few nice 2 wheelers around with clean bodies. After a ton of searching builds I wasn't able to get any info on the shackle mounts for the back end of the front leaf springs. Is the hole in 2 wheel frame to mount the shackle bushing? That's the only thing in question for me. Thanks for any help!!
