Re: 1971 C/10 to K/20 Conversion

Today I had a fun adventure. I got tired of wishing I could find the right 14 bolt FF on Craigslist or at pick n pull.. I have tried several yards in my area and no luck. I have a '71 and the leaf spring perch witch is 40.5 . I know that a 14 bolt from many 1 ton trucks have the 40.5 spacing. However many are dually axles or C&C axles. Well today I totally lucked out. I know of a woman that owns a couple acres of old auction land with many Chevys rucks that were abandoned there. I found A 14 bolt out of a 77 camper special 3500 SRW truck. It has the 40.5 spring width and a 4.10 ratio. Absolutely perfect for me. The only mods I plan on doing are welding the shock mounts to the front and possibly a disc brake conversion. Anyways I am really happy I got the complete rear end with wheels and tires for $100! It was a pain in the ass to pull out in a muddy field but I had a buddy help me and we made it work. Of course I can't leave anything alone and I have to make it all pretty so I have already started scraping the crap off it with a screwdriver and degreaser. I will post pics tomorrow after I pressure wash it . I plan on painting the housing. I want to run the gears as is because they look great. But there is a ton of backlash I mean like .030-.040 or more. I will check tomorrow. Oh yea.. I'm gonna put a Detroit locker in the carrier as well. I wish I could run a locker up front. But with a Dana 44, 35" tires and a 383 stroker I am afraid that I will be snapping axle shafts in the 44 with a locker. I feel confident that I won't be hurting the 14 bolt with a locker.
