The metro ones def. look small and seem like they would work well. Do you know how/if they would work with a full sized master?
It's a poor idea to mix a booster with a different master. I know a lot of guys that are using the geo metro booster and master with all kinds of different brake setups and they work very well. Just get the whole setup and you'll be laughing.
This seems like a lot of messing around just to spend some money locally, especially when the bracket you bought will probably work best with the Speedway parts.
Having everything figured out before you start putting it together rarely happens on a hot rod where everything is custom. You need to start putting in parts to see how much room you have and how everything fits. Without doing that it's just a wild guess. Some things on my truck changed drastically because I thought I knew how they would work and then when I went to do it, it wouldn't work the way I thought.
