So I have a 1996 Camaro z28 with the 6 speed... and a few other things.

I'm looking for a water pressure gauge, is there even such a thing? I just want it to be there so I can tell if my cooling system has sprung a leak somewhere...

And, has anyone done a battery relocation? I'm curious, but I want it to look good. I don't really need the weight change...

Lastly, What could I do with the coolant reservoir after the battery relocation? or even before the relocation, as long as it works well, and looks good...

Thanks in advance!
