Hopefully this is an easy one. The shop rebuilding my engine lost the two studs that go in the middle two mounts for the jackshaft into the intake manifold. I can get the diameter and thread pitch from a regular intake bolt, but don't know the exact length. If I recall correctly, it should be +/- 3" or 4" long.
The shop that lost them is willing to make me new ones, but we need to know the length.
Thanks in advance,
