I took my 79 distributor and my 91 distributor to a machine shop to have the gears swapped and it turned out that the 91 steel gear has a larger diameter hole in it than the iron gear. I said to heck with it and ordered a remanufactured dist from napa for an 85 mustang , I specified steel gear for it. The dist I got looks exactly like my 79 dist: It's smaller, takes the tall cap with the female sockets on top and...this is what bothers me.... has a shorter oil pump shaft. Now I know it engages the oil pump because I see the oil pressure go up when I start the car. Should I be concerned? Also, what does a steel gear look like. It seems to look exactly like the iron gear on the old distributor (stupid question, I know, but the 91 steel gear is...well.... beefier looking)
