Went to do some work on my car tonight and found the bolt that goes thru the rear engine mount is gone. Does anyone know the size, length and thread size? I was hoping maybe I could go to AutoZone or someplace else and find one that I can use as a substitute. Wish the parts department at the dealerships opened on Sunday!!

 

The length should be at least 4 inches long from base of the head on the bolt. A m8 type bolt might be the right kind. Home depot or Lowe's might have them. Just try different ones.
