I am in the middle of a frame off restore on my 76 K15. Frame actually goes off to powder coat in a week. I have a 6 inch RC suspension kit being shipped this week, and the plan was 37s on 15inch rally wheels, (85% sure on the wheels, 100% sure on the 37s)
When searching for an engine rebuilder for the 350 i came across a 76 K20 with a fresh motor for cheaper than a rebuild. So i bought it as it came with many other takeoffs i could use. I checked my 1/2 ton rear end and it has 3.73 gearing which wont do with the lift and tire combo. My question is, when i dive into the 3/4 ton which i was told is geared low, is it possible to use a rear end from a 3/4 ton and convert it to a 6 lug vs 8 lug? I know this is a dumb question, but i dont know any better. Trying to decide what to do, and no i have no idea what model rear ends they are. Need to dive in more, i want to keep 6 lug because of the rally wheel route. If i can use 3/4 ton axle with 6 lugs great, (if gearing is right) if not i gotta regear the 1/2 axle. Either way 3/4 ton will be parted out for 2 weeks before going to a pick a part most likely. Thanks!
