Rear leafspring shackle measurements needed

They make lowering blocks they keep the geometry of the spring right no binding. Mount between the axel and the spring. Just sold a set of 2" Way safer way to go.

I totally just had a dumb moment. LOL

I never thought about lowering blocks. LOL. And the silly part is is I've used them to raise and lower trucks in the past. LOL.

Thank you very very much for the reminder. LOL
