Well, I soaked my mounting bolts for the past 2 days with PB Blaster. I couldn't stand it any longer so I went out & checked to see if they would turn and was able to get every one of them to turn freely with a rachet

. This is good, right?
Ordered the new body & core mounting kit today so will see if my luck holds out. Hopefully this will cure the problem of my front U joint thumping the trans tunnel.
