There are 6 screws inside the fender well, turn them slowly. You might be able to remove only the Master Cylinder, from experience the Vac Booster is a bit of a challenge but what's new ? If you remove the side grill you can reach up to the canister to hold it as you unscrew the last 2 screws.
Best of luck, if I can help ask and I'll do my best to answer.
First one looked great but when I prepared it for paint it was coated in body filler. It made it air tight....or sort of. I stripped it all back and got welder to braise it up but we gave up as there was so many pin holes.
Imported a second and that is much better have not got around to installing....hopefully soon if I need to change the booster.

Not holding vacuum. Will need to have it sandblasted and then look for crack as I don't see any present after cleaning it. It may also be a bad seam. Fingers crossed.
The windshield area does look really good for making it all these years. A lot of cars aren't as lucky, I know I was not.

What a surprise I got! I was amazed at the time that all of this was hidden. An eye opening experience. All of that was hidden from me under the windshield trim. I thought I bought a nice original 69 coupe.

It was quite a relief to find no issues. Judging from what I've seen on the forum I've been blessed.
Thanks for looking RVZIO

Butyl ribbon is easier and less messy than urethane sealer that is used on later vehicles. I'll avoid the butyl vs urethand debate here.This debate really bugs me.
