i don't think the pedal assembly is going to work 2 different body styles not a big deal. you can get the pedal assembly from any 84-88 truck or 84-89 4runner. the crossmember everything will bolt right in. the driveline may be different but one from a 5speed 84-88 std cab short bed or 84-89 4runner will work for the back.the bast way to do the wiring take all the efi stuff from the 86 and put it on the engine going in you will need basically the block and head from the 94 everything else take from the 86 exhaust manifold, distributer,upper and lower intake, all the intake piping, airbox, mass air flow and engine wiring harness its a very easy swap. pull the kick panel off the passenger side unplug the ecu and the under the dash harness from the harness going to the engine thru the fire wall and you can pull the harness thru the fire wall and the whole harness you need will come off with the upper and lower intake. im not sure where you are but im in washington and i have a couple pedal assemblies laying around if your close you can have one.
