Interesting. My FIL had this rebuilt once about 25 years ago. That, and what appears to be a replacement exhaust manifold on the passenger's side, would explain the differences in the bolts. My truck is a Federal Emissions truck (no AIR pump), but has an AIR pump style exhaust manifold on the passenger's side.
