Hi, I am restoring a 66 K code with a Sep 65 build date. My question is should there be locking tabs on the exhaust manifolds (headers) for a 1966? Thank you.
Did you look in this forum's library under topic "Mustang Hardware Spreadsheet 64-66"? There are two files, one by part number, the other by use (aka application - "AP"). The use of "tabs" for exhaust manifold bolts is date dependent. Look it up.
(My intent is to point you in the right direction for answers to your questions so in the future you can be better informed.)
