A friend of mine got a toploader in on a trade and I am considering it for my Fairlane. It is a HEH-P 64 mustang 25 spline model, but has a Falcon extension housing on it which would work fine for my 64 Fairlane. The question is will that Falcon extension housing work correctly on the Mustang case and tailshaft? And is a Hurst shifter readily available for it, and is this trans the early small bearing case? It does have the dual pattern mounting holes at the bell housing flange. Thanks Dwayne R.
