68 c10 disc brake conversion using 71 c10

[68black_betty]

i found a guy parting out a 71 c10 with disc brake front and rear end still there. i wanna convert my 68 to disc brakes, ive been reading up on it and some people are saying to go with 73 rather than 71-72 due to harder to find parts. will it all just be basic bolt on or will there be welding and cutting involved, anyone that has done a conversion like im lookin for any info and suggestions on this project,, also is the 71 worth it or should i be looking for a 73 on up?
