HELP!!! I was starting to put my "A" back together and ran into a little problem. I thought I would just put in some bolts to secure the manifold. THEN I discovered the dang things would not tighten up!
When I took the manifold back off I discovered the 3/8 bolts would go into the block holes but I could just wiggle them back out by hand. When I checked the JD parts manual I discovered they were supposed to be 7/16 inches. I also looked real close at the old studs that I sawed off and discovered they were a square cut thread on the block side!
SO - any advice???? I really do not want to put a stud back in place. I think I would rather have a set of bolts. I'm thinking of re-taping the holes to a taper cut thread -7/16 in size.
