I have those covers and only issue I had was the dang grooves around the bolt holes is there to look pretty, not to help with bolts. I had to get studs to mount covers and then long wing nuts to really be able to tighten them down. Major PITA.
I have an alt and not a generator but just a heads up as you may run into the same issue. You might get better help if you post a pic or give us some more specific info on your car. I assume since these are SBF covers you have a 289 (64-66 since you say generator)
You may have to get the regular height covers, these are tall covers.

Thanks Brett, yes I have a 289 on a early 65 Mustang. The valve cover on the driver side lined up perfect but not the passenger side. Is there an aftermarket generator bracket sold any where? I have searched and couldn't find anything.
I thought about grinding the bracket but not sure how much success I would have the bracket is solid cast iron. Thanks for looking at the pics for me. Have you ever heard anyone talking about a smaller more custom generator bracket?
