Thanks to all who have responded. Just got back from racing in Homestead - I'm involved with a new series - American GT Challenge. Anyway, to review, I was able to get all of the rear suspension bolts (except the shock mounts-but that is another story that is already done)apart and removed in the fashion in which they were designed. If you look inside the bushing sleeves, there are several "points" that the bolt rides on inside the bushing, ostensibly to prevent the bolt from rusting to the sleeve. I have already used a drift punch (considerably more beefy than a center punch) and BFH (3 lb hand sledge) to no avail - and I mean it didn't budge. I will revert to plans B and C as mentioned in several of the other posts, and will update upon execution of said plans.
