We have developed our FD Pressure Chamber Bracket kit based off the 99+ RX-7 design, this is a direct replacement for the OEM bracket, no modifications needed. Our bracket is a great upgrade for people that have installed Efini Y-Pipes or Intercooler kits that eliminate the OEM crossover pipe.
Our Pressure Chamber Bracket is fabricated from laser cut steel, it is then Powder Coated Black to prevent corrosion. The kit comes with hardware for easy installation.

Good idea to make these, I've been running my OEM+ sequential M2 medium IC setup with out bracing that tank for a few years wondering when that 1 tab UIM mount will crack.
Ever thought about making an aluminum replacement pressure/vacuum tank?

that link is broken btw

 

Strange the forum changed things

Dang it can you just drop these all at the same time so I just pay shipping once!? I already got to use the alternator bracket lift hook, Love it!

 

Nice work, just a slight edit, Mazda fitted these to all cars made December '95 and onwards, same time the aluminum crossover pipe was introduced .
