As long as the bell housing and converter is for the correct flex plate size (157 or 164 tooth) yes it will bolt up.

157 or 164 teeth. You need to figure out the tooth count on your flex plate. Any parts store or even on line can help you know if you where going to buy a replacement flex plate. Google is your friend. Yes a 351 flex plate will work with a C4 if it is the correct size for the bell housing. Like I said before the come in 2 sizes to fit both 157 or 164 teeth flex plates. The stock starter will bolt up.

Your 67' transmission most likely has the 157 tooth bellhousing, which is the one that I'd recommend using due to clearance issues.

The late model 351 should have a 164 tooth flexplate. Luckily, 351 and pre 82' 289/302 flexplates are completely interchangeable.

There is also a third variant that was used on V8 Mustang IIs that is even smaller, just worth noting.

The 157 and 164 both use the same starters. If you don't have a starter now, I'd strongly recommend using the late model PMGR unit. It requires some minor wiring changes but is far superior to earlier versions.
