Which servo came factory on the C-4 trannys? I have a '78 C-4(case fill) and I want to do add a manual valve body and upgrade to either an "H" or "R" servo. I was wondering which one it has already.
Also, where is a good place to buy an upgrade servo?
Which one would be better...the H or the R servo?
