My RB in my 68 Spool type K frame has a factory heat shield in it.Looks similar to this one.

Looks a lot like the heat shield that are used on a big block A-body. It also solves a mystery that I had with two heat shields. They were almost identical and now I see that one was for an A-body and one was for a B-body.
