IIRC I used 9/16-18 bolts to do mine and they work great. It is possible they are a 3/8 NPT. I looked at those as well and others have used them successfully. I just bought what looked like it would work the best.

well the 3/8 npt plugs are too big and the 1/4 npt go in but are loose, so i just used the original plugs and crimped them real good.
