My eBay purchase arrived today. The selling point was that it included the blank heat riser as part of the deal. I’ll remove the old threaded studs and install new. I don’t see any cracks in the manifolds, so I think my $96.30 which included shipping was well spent.
Take notice how the DS manifold has threaded holes on the end for the alternator. Vendors sell the correct bracket. Here’s a picture of a 1966 C10 283 with the same manifold/bracket setup. Last picture shows same style bracket with the alternator.
