I am needing to remove the gearbox mounts in the tunnell of the 1969 thou to fit the toyota T50 gearbox.

What methods have youguys used to remove the mounts (which are spotwelded) with minimal damage.

1 - remove sound deadener from inside of car, and locate the spots. Then drill them out.

2 - grind off the mount from underneath. - very slow and crampt.

any other methods
?
