Your solution is fine. Most of the time a little firewall flex is tolerable and most folks don't know if their car has any or not. The symptom I was having was insufficient clutch master cylinder stroke (because the firewall was moving away from my foot about 1/4 inch) and my push rod was just barely long enough. My support rods from the firewall to the inner fender fixed my poor disengagement problem. But the real problem was that my clutch push rod was too short. When I lengthened that, the problem of insufficient stroke was REALLY fixed, and I'm pretty sure that my clutch would have disengaged better and the firewall reinforcement might not have been necessary. Be confident in yourself. Lots of folks think that their way is the ONLY way. But whatever works is ok by me, and your car. If one thing doesn't work, keep at it til you win.
