Im having my XLR8 engine mounts put in but my mechanic doesnt want to use washers for the side mount bolt. Does anyone know what size and pitch bolt i need, or is it just a 10x60 without the collar?

 

It should be 12X1.25 and I believe the bolt we use is 5mm shorter so 60mm should be good.

 

Thank you, but i am having an extremely difficult time finding a partially threaded M12 with 1.25 thread pitch that is 60mm long
any chance you can provide a link to order one if you can find it or someone else is welcome to chime in

You can also just use a couple washers. It will do the same thing. Use a flat washer and a lock washer or two flat washers.
