My stock engine mount (the upper one in front) stripped and bent. Mansson titanium had a part that barely fit. I had to turn the brackets inside-out and replace the spacer with nickel washers from the local machine shop [4 cents each]. I also replaced all of the smaller bolts. Everything fits snug now and there's no slop in the drive train due to a loose engine.
I used their nuts on the cylinder head and there's no more problem with rust.
