In the catalogs, they show rebuild kits for C4's with and without plug in modulators. I haven't taken the modulator out of my son's 1970 C4 yet. Is there a quick way to tell which I have? I'm heading to Transtar in the morning on the way to work to get a rebuild kit and need to know which to get.

IIRC, the push-in modulator has an external clamp and bolt which hold it in...the screw-in one has thin wrench flats...

It's been awhile..*G*
