I have a '77 vette with power steering,tilt and telescope.Going to be ordering a new coupling through CPP(got a gift card from a raffle) and am I correct in saying the spline count is 30 with a 3/4 dia.
And does the coupling have a flat spot on it.

you should measure yours , I think all c3's have the same size and mines oe.

Yes "that" place.If they do 20 questions again i'll just buy some swag and get my rag joint from a real vette supplier.

I did some more searching , It seems there's a 1" 48 spline version and a 3/4" 30 spline version. I dont know how accurate that is or what the reasoning is, it came from the borgeson site. measuring yours would still be the best.
