Had to grind the tabs and the clamps to fit to an original manifold. Not whining about that so much. But 1/16" wall thickness on a casting is just [censored] poor. My last project was a 69 Mach 1. Many repro parts were so bad they were unusable and were sent back. Suppliers should realize we would pay more for a quality part that actually fits!Heading to Charlotte Autofair next month to find as many good original parts as possible.
