foot Pedals

i just bought a 71 chevrolet custom 10 but i am 6 foot 2 and the pedals are very far forward and i like to right with my legs stretched out so i was wondering if any y'all knew how to maybe move the pedals back and move the seat back as well. maybe i any of y'all have ever had this problem do share and shed some light on the solution PLEASE!!!!

I have the same problem with my 37 chevy truck. I'm only 5'10" and my knee is hitting the steering wheel. Since I have about 4 - 5 " of firewall to play with, I'm going to extend it for extra leg clearence.
