Check the proportioning valve that’s circled in your photo.

The master cylinder is unique to 1967 disc brake as I show in the photo of the ‘67 HO I restored years ago.

BTW, your WT 335 HP has the added HO exhaust manifolds which require a completely different engine wiring harness.
But that’s another day.

Good luck on your project.

Looks very much like the one I got from Inline tube years ago, when I swapped '67 power disc master onto my '66 Chevelle. I had a pair of '67 calipers and rotors, but sold them and went with '69 single pistons from, I think, a '69 Camaro. I don't have a good pic of it from the same angle, but I can take one, if wanted, for reference.

Hi Bill,

I had someone question me privately about my photo of the smooth rounded master cylinder on my restored ‘67 GTO that was built at the Fremont factory with power front disc brakes.

Here is a New ‘67 RA from a magazine test article showing the same M/C and Proportioning valve.

My old '67 had the same style master, not sure if it was the original to the car, but the disc brakes were.
