What pedals will work?

[Jspohr]

Decided to go with the mechanical clutch (not hydro) sm465. I've tried searching to see if square body clutch pedal will work, but don't see anything. To my knowledge, there were no factory mech clutches in 90's models chevy trucks. Trying to figure out if there's any junkyard setups that will work.......

Also, can I used the factory automatic brake pedal or does that have to be swapped also.

thanks
