I heard a rumor

[nonstop]

I guess this leads me to more questions than less:

First, would it be possible to run a grade 8 bolt through the top hole and use that as the pivot if you tack welded the head to the pedal and used a lock nut on the other side (I still don't trust my welding to something as crucial as the single pin charged with stopping the vehicle)?

Second, I love my hydroboost and it was night and day when I did the conversion, but why does hydroboost have a higher ratio than the vacuum booster when hydroboost puts out a lot more pressure to begin with?

Thanks!
