Welcome. Could you do me a big favor? The moment I scrolled down to the firewall picture, it jumped out at me so fast that I almost fell out of my chair. What you have is a correct ’69-only master cylinder on your car, and they are 100% extinct. Not only is the master cylinder 100% extinct, but the knowledge base about the ’69-only master cylinder is extinct.

Here’s a picture of a correct ’69-only master cylinder. Please post a picture that better illustrates the fittings that have the red and blue plugs in my photo.

It’s late, I’m a lurker, and I had no intentions of posting anything, but I was so floored to see a correct master cylinder that I dug mine out from deep-freeze storage, took a shot and posted the picture, rather than hit the sack, where I was planning to be at this moment.

Again, please post at least one shot of the fittings, and I’ll make more comment later.
