I'm getting ready to order a Universal booster for my 63 Dynamic, was wondering if anybody knew offhand that what the bolt pattern was for the firewall
thanks in advance!

There is no specific torque pattern .
All bolts should be tightened incrementally in a criss cross pattern .

sorry should have clarified, I was looking for bolt spacing to order a Universal booster.
thanks though!

I have never heard of universal booster. Used to order a booster for a 63 Olds or a 69 Impala or whatever...

The street rod world sells lots of generic brake boosters. They are "universal" in that they will fit whatever firewall you drill to match the pattern on the booster.

My suggestion would be to order the correct booster from Booster Steve (formerly Dewey).

What type of booster do you have now ?
There were two types , Bendix or Moraine .
Bendix had four bolts holding master cylinder to booster .
Moraine had only two bolts .

If you are lucky enough to have the Moraine booster then get it rebuilt and use a '66 Cadillac master cylinder on it for a dual brake system with right side outlets that you will
need .
I would not suggest mickey - mouseing around and trying to install that " one fits none " universal booster .
