Pedal Assembly interchangeability?

[Wrenchdoctor]

Greetings,

Would the hydraulic clutch setup and (more importantly) the pedal assembly from a '90 4.3 c1500 bolt up to an '81 c-10?

I have a good friend getting ready to part one of those trucks and I am trying to think of things I can get to put away for later projects.

My truck is currently an automatic, but I would love to get a 5spd for it. Since time is on my side, I will eventually gather up all the parts necessary to facilitate such a swap. If this works, I am well on my way

Thanks in advance
