I got lucky in that I was able to open up an existing hole to the 1/2" x 5/8" rectangular size required by the throttle cable. Once the cable was attached, the Allstar pedal assembly was put in its approximate location to verify everything is going to fit. The location of the pedal pad is going to drive me nuts until I find it, or buy another one.
I got up this morning and wanted to install my new Allstar brake pedal assembly. Problem is, I went looking for my Lokar BAG-6005 pedal pad and couldn't find it. There is a box somewhere with the pedal pad, my blue dots, and some bondo and other items which shouldn't be left in freezing weather. Not sure where I put it when spring hit.
Anyway, I decided to move on to the accelerator pedal. I fabbed up a bracket to mount a 1989 Chevy 1/2 ton pedal. Holes were drilled so that plug welds could be put in when I am filling the many other holes in the firewall. For now, the bracket was tacked in place. The pedal was modified to accept my surfer pedal cover. Note how the packaging was cut and taped to the pedal to prevent scratching.
The engine was shifted around until there was firewall clearance and fan clearance. It was determined the front edge of the frame mount needed to be 22 inches back from the front of the frame. The engine and tranny were removed. The frame mounts were positioned and then cross checked from the front frame holes and each other. Finally, four large tack welds attached them to the frame. Tacks were used due to the learning experience of having to cut much more complete welds out previously.
1. Under dash booster/master cylinder.
2. Under dash air conditioner.
3. Passenger side foot room.
You can have two out of three.
The initial mock up of the under dash booster/master cylinder showed that the pedal arm is too long and will have to be shortened. The master cylinder will need to be replaced with the type that has no reservoir. The AC unit will hang down real low.
At this point, I am 99 percent sure I am going to go with a through the fire wall mount. The booster and MC will go out next to the engine. I'd rather not, but you sometimes have to compromise.
