It's funny how there are some parts in this hobby that are just plain tough to find. Correct leaf spring bottoms with correct dates are definitely one of them. Obviously it's a super small detail, but to someone trying to return their car to 'correct, as released from Shelby American' condition, it's important. I can't imagine many folks kept their original leaf springs when they replaced them way back then. I'm sure the big dogs hit most if not all the major junk yards already looking for parts like these. That must have been a fruitful endeavor back in the late '80s/early '90s.
