That odd looking bracket above and on pg. 148 of TBON is a Ford Part, C2OZ-9741-B. Many times, that Ford part was left on the Tiger engine under center bolt of valve cover.
1224854 - Bracket listed for MK I - short - no drawing date listed
1229919 - Bracket listed for MK II - long - this drawing has a 11/24/64 date
This date could put the long bracket in the L2KA engine group but I doubt that very much. The short bracket was ordered in quantity which needs to be used up. The 2nd bracket needs cost evaluated; tooling ordered, then part cut in; that takes time. There is no indication of the cut in date or Vin # cut in.
My F21KA engine has the longer bracket and I know 1 L2KA engine that has the short bracket and that Ford Part. I have pictures of the short bracket on S6KA and S27KA engines.
