4wd Disc Conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Brimow525 · 04-08-2004, 09:01 PM

I did a search and saw a lot of info about 2wd conversions but not alot about 4wd. I have a 70 K20 with D44 with drums in the front and a Eaton in the rear. I want to either convert the front to drums OR swap out both rears for a newer style with front disc. 4:10 gears right now but not really concerned about what gears but more concerned about what vehicles I should belooking for, for the donor parts. Buying a kit (although is a great idea) out of a book is just too much in my opinion. Can I look for 73-88 rear and pretty much just bolt on? Or do I need to stick to the mid to late 70's for the easiest conversion. When I do this I am going to replace every bearing, seal, bushing etc. before it all gets installed. Any info or help as to what I need to look for would be great. I am a newbie at the conversion stuff, so pro's, go lite on me.

if you want to swap axles, then you can swap in a dana 44 from a '71-'77 K/20 truck or burb. you can also use the 10 bolt front axle that was used into the 80's. and if you're lucky enough to find one, you can use a dana 60 from a Dodge 3/4 or 1 ton, or a 1 ton GM, as long as it will fit. good luck in your swap.
