Rear Motor Mount Bolts Stuck

[linmictil2]

Morning: Whenever I had a problem with "stuck" bolts I put the heat to them. Get them cherry red and a blast from a hammer always did it for me. Careful not to melt anything .
Just a thought.. Have a good one mike

Hah. My first thought. But I really don't have any idea how much abuse the motor mount castings can take; all I do know is that castings are relatively brittle. Hammering on them doesn't seem prudent.
