The 67-72 drivers front spring hanger strap and shackle stop thread

[Richard]

Wanted to note the 1/8" gap would be for stock type flat/ slightly negative arch springs. The springs get shorter as suspension cycles. When running positive arch lift springs that gap would need to be larger (or stop removed) as springs get longer when compressed. Damage may result with spring constantly hitting stop. Then again, most aftermarket lift springs do not move much
