For our Alfa engine to go on a Hewland, here is what I think I've figured out for different input shafts:
11.56" - Formula Ford - what I think we have now in our Hewland
10.8" - What I think we need
10.38" - Super Vee size
10.06" - Another input shaft we got (we got it from the shop that took our engine off a Hewland many years ago, and replace it with a Ford. They think it was the one on the car.)
Some questions:
(1) Anyone have or know of a 10.8" input shaft?
(2) Anyone know what a 10.06" input shaft might be from?
(3) Is there a chance that there are different length input shaft couplings that might move the input shaft in our out up to .5"?
(Yes, I've never been in a Hewland box - maybe it's obvious the coupling can be only one size. But that's what would make sense if the 10.06" input shaft is the correct one).
