Hey Tuck1 , hope you are making out alright , never would want to hear a member is in distress personally beside the rig itself !!
I once had my driveline shift on my 92 XJ with the crossmember off for a mount swap and shaft lube when the floor jack sank into the dirt even with a small plywood square under it . The advantages of working in your driveway on dirt between two cement drive pads. I too have done many jobs on many cars there (if my driveway could talk, stories it could tell ) but when you have to do an emergency hulk hogan and upright the floor jack again trying to center the trans to put the mount back up and salvage all ten fingers , you might want to ask yourself , should I have asked for help ? We always brave it alone , pride runs deep , but please reassess your plan of attack and you will get 'er done . By now , you probably already did , I hope !
Just caught your post now and it jarred my memory of my misadventure . Post when you can , hope the worst is only a stressed motor mount as I respect Bounty_Hunter's assessment . Really hope ALL is well , not even a busted mount ! Go easy bro. .
