Getting under the dash is a pain. Here is a video.

Seriously? Full day into the 2nd???? I see one screw head on the engine bay side. Can someone outline the steps on a 70? I thought I should see 4 bolts all on the engine bay side and then just unhook from the pedal on the inside....and of course the brake lines. Should I replace the master cylinder too?
Trust me, its all day. The nuts are tough to get at under the dash and the MC was a tough task also. I replaced the MC, it was $25 from auto zone, Both booster and MC were about $100 or so

Ok, gonna pull the trigger and order the parts from WCCC. Don, I'd appreciate you or anyone else double checking me on parts before I place the order.
I've got a 70 Eliminator, 351C, Auto with power disc up front and drums in back.

I'm ordering...
Booster

Bushings and hairpin. Should I replace anything else while I'm at it?

Also, WCCC doesn't have a master cylinder in stock so how do I pick from the multitude the local auto parts place will have?

How about this one...

I saw some horror stories about brake lines not fitting certain master cylinders and having to re-flare the ends. I don't want that.

If your Cougar has the OEM Bendix master cylinder, you might consider sending it to Booster Dewey for rebuild, or exchange. Does your local have O'Reilly Auto Parts nearby?...or multiple locations that are nearby? If so, spend some time checking to see if any of the stores have rebuilt master cylinder units in stock. If so, go to the stores and physically look at them to see if any are Bendix units. You might get lucky. I have found them in the past. Whatever you decide, consider keeping your original Bendix unit (if you have it). If you need to go short term with a generic rebuilt unit, you can still have your OEM Bendix master cylinder rebuilt for future use. Best of luck, and hope the end result turns out well.

YES!!!!!!!!!!!! I finished removing everything in 1 hour and 15 mins. I might hurt all night from playing contortionist under the steering wheel, but it's done. Here's what all I did... removed air cleaner and unhooked vacuum hoses that were in the way. Siphoned brake fluid from master cylinder. Removed brake lines from master cylinder. Removed export braces. Removed master cylinder. Removed 4 brake booster bolts from under the dash and one on the outside. Removed brake light switch. I'll post the pictures next. I assume the brake booster is the original but I'm guessing the master cylinder is a replacement.

Don Rush, you'll be getting this brake booster soon!!!! LOL

...and all bolts were 9/16. I used two 6 inch extensions with a swivel for the under dash bolts.

A secret....
Prop open the hood....
Remove the dr hood hinge spring & you won't have to remove the export brace (or one side of the factory brace) to get the booster out.

That mastercylinder should work fine, eastwood has some brake fluid resistant paint I spray on my m/c so they don't rust.

That Eastwood paint you're referring to works very well indeed. As far as rattle can paints they have some good stuff.
