Leaf spring shackles ? B body vs e body

[Purepony]

I have a 74 challenger that needs rear leaf spring shackles but I can’t find them. I read somewhere I can use b body shackles but it will be a half inch shorter. So wouldn’t that lower the car ?

I wanted to ask if anyone’s used b body shackles on an e body

Or does anyone have a set of good e body ones for sale ? Preferable in ca so o can pick them up

Thanks
