The big block frame stands are different to offset the engine to the right . I was wanting to know if the rubber mount was different on the left to allow for the anti lift bracket thickness .
That second layer Charley is talking about is the door striker reinforcement seen in Jerry's picture in front of the rusty tube on the right of the picture .
I just looked at mine , it has that same looking thing its just a stain from water getting past the quarter window weatherstrip . feel inside you probably wont find a step like a panel would have .
Is the mount that uses these brackets shorter than a regular mount to allow for the thickness of the bracket , or does the engine set higher ? How thick is the bracket ?
