A fun show to check out. Mid '70s Monaco painted up as a Bluesmobile replica.

They replace the brake booster with a new one, from who knows what model.
They see that the new booster accepts a 2 bolt master cylinder, but the master cylinder
for the car has 4 bolts.

Instead of asking anyone who knows something about Mopars and then bolting on an M body master cylinder, they actually make a template, take a saw, cut the 4 corners off the iron master cylinder, drill two new holes in the iron
master cylinder and mount it up.

It was cool they made it work, but it demonstrated such blatant Mopar ignorance that it made for some good entertainment, in my humble opinion.

Wish I knew the techs on the show, I'd send them a picture of an M body master cylinder, with a short message "This bolts right on".
