lowering blocks

Just wondering where the best place is to get 1" lowering blocks for the rear end for a 67? Thanks

Most any auto parts store will have lowering blocks.

They usually call them lift kits and may include longer u-bolts, but a one inch block is a one inch block.

Try and stay away from the hollow ones if you are making decent power. I broke them to pieces. If you find solid ones let me know where to get them.

Maybe these solid blocks would work:
