Engineering advice please:
The photo shows the rearmost block to crankcase stud hole, which has been tapped 7/16 BSF and which had a stepped 5/16 stud.
How to proceed? Acquire another 7/16 - 5/16 stepped stud, which don't seem readily available off the shelf, or plug and tap to 5/16? The 7/16 thread appears good to me. There's not much meat left in the crankcase so I'm not keen on removing any more material.
