Master Cylinder mounting

[1moretoy]

Hey all, I'm going to run an electric power assist master cylinder and need to figure out a way to mount it. The master cylinder is a standard 2 hole but I have multiple holes on the firewall. It's been a while since I took the car apart and of course I can't find the plate I had. Does anyone know where I can get one so I can mount the new master? Also, what do I do with the two studs sticking out above? I was thinking I could cut them, spot weld and grind flush?

They make adapters for your conversion.

I think I have the plate you need but you'll still need the adapter that Xcudame posted the link to.

I believe you still need the two studs above to help support the engine wire harness if you intend to install one.

Got it. I don't plan on running my wiring that way so I guess I can cut & weld them. Is there a good source for the plate and adapter bracket?

Before you cut them off, check inside.
I believe the structure supporting the pedals use those bolts.
The whole support plate on the engine side, is for reinforcement.

Yeah, I was thinking that too. I could always weld that area under the dash to the firewall as well.

Xcudame posted a link to order the adapter and my plate is the exact same type as the above picture. You're welcome to the one I have for the cost of shipping.

Thanks for the offer Heminut, I actually found my plated today, woohoo.

Thanks Xcudame, I purchased an adapter plate similar to the link you provided.

Finally, thanks to katfish for the photo, it helped a lot.

Rear brakes should be delivered next week. What size master would you guys reccomended? 14 inch willwood front and back, six piston front, four piston rear.

I think you'll need bigger tires to clear the Willwood calipers and green bearings on the rear axle if I remember my build correctly.

Yup, I'm going 18/19 wheel combo. I have a 9" with 35 spline axles, detroit trutrac and 3.00 gears.
