Re: 66 toploader conversion

It uses the same 28 spline trannsmission yoke (assuming the toploader isn't the rare 31 spline model.) The driveshafts are also the same length too.

Also, the crossmember is identical and the toploader will use the same rubber tranny mount. No mods are needed here.

He can use either a factory shifter (not recommened for hard shifting) or a Hurst Competition Plus which will work in the same floorshift hole, even with a factory console.

The starter will be different as the manual starter has a different mounting flange than the automatic.

My brother swapped a toploader into his 67 (factory C-4 car)and reused everything but the starter...

I have seen some variations of tranny mounts but this was due to different years..Some toploaders use an inline bolt pattern for the mount where I believe all c-4s have the mount crossways to the centerline of the trans...My toploader mount has the bolt pattern for both setups so it would work on either trans..
