G'day David,
Just going over this amazing thread of your's. I think youve managed to override just about every bastard obstacle you could run into restoring one of these trucks. Very very well done!
My two cents and limited knowledge of Chev's, there are no rubbers for the brake or Clutch pedal so you wont have to expend any time there.
That accelerator pedal youve fitted is very similar to the one in a 13 Cab 2WD Chev. I know its not original but you can always change it at a later date if you come across the right one.
Great stuff, great info, great effort!!
