I'm in the process of updating my brake system on my 66 Ford Unibody truck.

It's already received a front disc brake conversion (GM style) and STILL has the single mater cyclinder & factory drum rear brakes.

I did pick up a dual GM style Wilwood master to replace the single res. & wanted to add a booster.......

Now my question:

Do I need to utilize one of those monster sized GM boosters or......can I substitute something a bit more.......better suited for the smaller space I have?
