I have Hotchkis 1.5 lowering leafs on my 67 and I'm running a Moser rear with a 4 deg. pinion shim. I wanted to lower the car another inch so I installed some 1 inch blocks along with the 4 deg. pinion shim and wanted to know what you guys think and your opinion. I want to make sure it is safe. I wish I could find a 1 inch block with a 4 degree angle all in one. I went to the spring shop they wanted $310.00 to de arch so I though I would give this set up a try what do you think? I added a 4 deg. shim on the bottom of the spring shock plate just to keep it flat.
