Why are there spring perches cut off????? tell me you did not cut up a stock A body 8 3/4 :(

are the balance weights are rectangular it is probably OEM, if round probably not. BUT the tapered ends makes me think it is OEM

Perches are off another rear end for my other 69 barracuda. Junk yard had it marked as coming out of a van. I plan to narrow that housing in the future. Thank you.
