question about my new old C10!!

[luis979motoring]

well fellas! i have the C10 bug!! I haven't even finished my 68, and I decide to sstart on a 87 C10... so heres my story....

I have a C10 that is a 1ton that i picked up from my old mans construction company, the truck is solid and in great shape(cab wise) now I want to make a short bed and I already have a frame and a extra cab. and bed. This is where I have the question, about 15 minutes before I show up to get the frame/ cab, the owner sold the rear end.! d'oh!! so now I have a complete donor truck, but no rear end. My question is, Can I use the old rear end that I took out of my 68 C10? even though it's a 6 lug, I was thinking of just getting new axles and all for the rear to make it 5 lug... what do yall think? would this work? or should I look for a different rear end? thanks for all the help fellas.
