Mono or Multi Leaf Perches

[mudjnky]

Looking for some different opinions on what to do. I have to replace the spring perches on the rear of my Wife's 68 Camaro. The previous owner welded them in the wrong spot. We are using multi leaf springs. To eliminate any possibility of rear movement I don't want to use the stock pads to insulate the spring. We are using the traction bars with J Hooks. Can I use the mono leaf mount to compensate for the spring thickness difference? Has anyone ever done this?

What do you think?
