One thing to keep in mind when removing the bottom 10mm nut off the engine shock, and then lowering the engine after finishing what ever you were doing.
I removed the 10mm nuts, large washer and rubber piece. lifted the engine to replace the oil cooler lines.
when I lowered the engine, I didn`t pay any attention to the shocks lining up with the hole they drop into.
I get all done, and see the shock shoved up through the top mount

. well that is a $50 fix

.
Luckly the nice people in the parts dept at PNP had a supply for me

.
It`s a crap shoot, but every once in a while a good one shows up.
A 7mm also fits the flats on the shock shaft to hold it from turning when removing the lower 10mm nut..
