wrong Wilwood master cylinder?

This is what you need.

depending on caliper piston sizes, pedal travel and pressure desired. Also, a proportioning valve should always be installed in the rear circuit. You NEVER want the rear brakes to lock up before the front.

I have the six piston kit from SACC, and the previous owner had already removed the proportioning valve but Scott had said with his kit it wasn't necessary. As for pressure desired, it's a street car so I'd say medium.

I installed a Wilwood Tandem Master Cylinder in my Pantera last winter to replace a failing stock master; rest of the brake system is all stock. In addition to making up new brake lines from MC to shuttle valve, I had to increase the depth of the IPSCO Adapter push rod and adjust the booster push rod until I got the preload I wanted--about the thickness of the washer I removed from the MC. I also had to trim the MC circlip a little so as not to interfere with the IPSCO push rod. Nice to have brakes again...

Ahhh yes, this is exactly what I'm going for, thanks. My existing pushrod is too long to put the IPSCO sleeve on it even adjusted all the way... did you shorten yours?

You have to remove the Wilwood push rod and washer from the MC. The IPSCO Adapter push rod slides onto the booster push rod, and the flat end pushes against the MC piston. The Adapter push rod would be better if it had a rounded end for this application, but it works with a little massaging. Hope this helps.

So turns out I'm not crazy or an idiot (well, at least not in this particular circumstance), and learned what the issue is, thanks to Scott at SACC. The booster and master that the previous owner had on the car used a longer pushrod than stock by about 2 inches, and that's why nothing fit. It was in my original pic but I guess not noticeable. I have the right Wilwood master, I just need to get a new pushrod or a new booster with new pushrod that is the correct length.

Thanks so much for your help figuring this out... and the moral of the story here is just to call Scott @SACC and get everything from him from here on out!
