I have a 66 mustang with a 289 and a c4. I'm getting ready to rebuild
the c4 but I'm getting alittle confused with the identifing marks. The
casting number on the tail piece of the tranny is c7op-7a040, if i've
done my research right this should be a 67 c4 off a fairlane/torino.
Now where i'm getting confused with is the 5 bolt bell housing and 24
spline input shaft. I thought I had read that those should be on a 66
and earlier c4 where in 67 ford went to a 6 bolt bellhousing and a 26
spline input shaft. There is a metal tag on the tranny with PEA M1 and
underneath that is C9APABM4. Another number is on the pump cover which
is C6AP-7D027-C. It is an aluminium bellhousing with casting number
RF-C5AP-7976-B. Any help with the numbers to find out what it really
is would be great.
You have a mongrel, there.
It looks like you have a Mustang with an earlier than '66 289, & a
transmission that was rebuilt/exchanged probably in the early '70s when
it was just an old car that someone needed a transmission replacment for.
I cross-posted this to rec.autos.makers.ford.mustang so the real Mustng
guys might be able to help out.
