need a little direction..

intalling a 78 2+2 L28 and plan on 72 SU's in an early 74260. My question is which harness should I install as I am concerned on the disributor hookup?

due to some common sense, it looks like I answered my own question. I would have to use the 74 distributor unless I was converting either the whole car to fi, or wanted to splice parts in.
