Thanks, Greg. I checked the Mount bolts yesterday and have two stubborn ones up front - they begin turning easily but then get tight. The mounts appear to have been replaced before. I have floor pans to patch first and that won’t be for a bit. Hopefully this will be a late fall winter project.

As I recall, the two up front have big (1"?) square nuts that have to be held with a wrench. I think I used a crescent because I couldn't see with the fenders in place. There are access holes in the lower firewall/cowl area where they can be reached with some effort.
The other thing I didn't mention is to keep an eye on the distributor as it will contact the firewall if you raise the rear too far. If you need the space you can just pull it.

Good tips, thank you
