Are the motor mount bolts, n0143291, reusable? They are described as self-locking.
I know a lot of self locking features are only usable once, but I'd like to be sure since this a high vibration application.
Most searches show no longer available.
Are lock washers and rated bolts suitable replacements?
My mounts came with a mixed bag of bolts, much like the car in its entirety, and I'd like to replace them appropriately when the engine goes back in.
