Anyone have a wobbly gas pedal??

About 2 years ago, I tried to tighten my gas pedal, as it seemed to flex way too much. Well, the upper bolt stripped where it was threaded into the weld nut, and so it would just turn, not loosening or tightening, and I couldn't remove it. Well, I got smart, and I put a Second nut on the firewall side, where the good threads were sticking out, so that I could tighten up the bolt. I was able to remove the lower bolt, and replace it with a stronger one, and did the same nut-fix to the firewall side of it as well. The problem is, that not just the mount bracket, but it seems that also the firewall metal, is flexing. When I step on the pedal, it twists slightly to the left(towards the brake pedal), by maybe 2-3mm. Has anyone ever had this problem? I intend to remove the pedal completely, reinforce the bracket with upper and lower welded-on plates, and am considering welding an entire backing plate to it, to increase its contact area with the firewall, to increase it's rigidity. Just curious if anyone else has had to modify their gas pedal for more strength.
Thanks for reading.

I come from a land down under
I recently converted my pedal into a DBX sensor and noticed on my old one it was VERY worn allowing a lot of slop.

There are no bearings/bushes just Metal to Metal contact between the bracket and shaft, this wear accelerated in my case due to the stiff return springs I needed to run to stop it sticking open.

Mine does have some play (2-4mm left-to-right possibly?), but it has never really bothered me? :icon_neut I dont feel the firewall flexing either.

Well, it also seems that the metal shaft which makes up the pedal's 'arm' is rather thin and flexible as well. I was thinking of trying to reinforce that as well.

Mine has a ton of play and squeaks sometimes...it also has a ton of resistance, you have to push it really hard to move it, and it doesn't move smoothly...I've been thinking about replacing the whole assembly as well as the cable for a while.
