Bob;
I know this well. In 1977 my first TR-6, a 1971, the first car I ever owned
(boy, did I love that car, Heck, that's why I bought this one), crack 2
mounts, and ripped the right front one out completely! (Those hole shots
will do it every time.)
I'm going to take the other side rear axle out, remove the driveshaft (I
want to replace all 6 U-joints anyway) and drop the diff, and weld away. May
the force be with me!
