Nex, I'm not Tom but the "forked 8" kit will only fit the I-6 distributor....the 2.8 distributor has a different centrifugal advance mechanism than the v-8 and I think all of the 4.3 distributors utilized the 7 pin computer controled module for timing control; there may have been some 5-pin 4.3 distributors but I don't recall ever dealing with one....fats
