Hello. How are you today? There are two ways to resolve our bolt situation.

  • You can use a good quality 3/8" self tapping bolt. Although your holes are 3/16" at the top , this size bolt will work for you. Just make sure the bolt is a good grade, hardened steel bolt. Also, use plenty of lubricant, as you are tapping your holes. Take your time, and this will work well for you.

 

  • Or you can also use a good grade, hardened steel, 5/16" bolt, with two flat washers, a lock washer, and a nut. This will work for you as well. Just put a flat washer under your frame, and a flat washer, and lock washer on top of your block , before you put your nut on.
