Hector, my front engine mount looks like it had a similar problem. That is the mount was a good 1/8”-1/4” too narrow and there was no room for the lower brackets. I wound up fabricating my own since the LT4 engine mounts have a different geometry than the LS.
One thing you may want to do is take it out and widen the bracket a bit.
Take a look at Kurtiss’s GT-R build page twenty five, he did a nice mod on his front engine mount to change the centering of his engine.
David, thank you for the info. I was using the Astro rivnut tool today in a tight spot and could have use the tool from Pegasus. Time to order this tool.
