LS engine mounts for a 1963 Pontiac GP?

Mark!! I don't think I've ever seen your posts here. I have a couple of pairs of adjustable mounts at the shop. This weekend is obviously no good because of working on Mike's car and the Mustang, but after that we can trial fit some of what I have along with that bare block I lent you and see if anything is close. So far, I've had luck with using GM "clamshell" mounts and the adapters.
