c-20 disc uprade question

[chickenwing]

Posting this for a buddy of mine who professes to be a "Fred Flintstone" type with computers.
He has a 69 c-20 (pretty cool truck someone put in an extra cab on it) He would like to upgrade to power disc and he wants a shopping list of what he needs to do the job.
He is not opposed to dropping down to 6 or 5 lugs. My thought was that the cost would probably go up if he did.
Any help appreciated.

I went out and got a 79 3/4 suburbans and took the front cross member out of it for the disc. It fit right in i only had to drill 1 new hole on both side.

I dont know how far you are from me but there is a 71-2 3/4 in a junk yard with disc and the guy told me $100 for the set up. I dont know what it needs or anything.

hope this helps Nick
