Tims turn
I've conceeded tower clamps on small blocks after 66
. I found no credible evidence of any other than one original owner of a 5/68 car claiming "thats the way it always was". Big blocks it appears the changover date was not concise as we see some 12/67 cars with wire clamps and cars as late as 4/68 with tower.
Brant, are you going to carry the C8 small block hoses with wire clamps?
