Since i'm swapping to the GM Compressor, all of the AC stuff is getting replaced. Knocked out the Evaporator today. Gotta say, this was much easier than i was planning on it being. Just unplug everything. Undo 2 bolts and like 5 screws in total and pull the box out.
Old cruddy Evaporator. Theres got to be a way to add a filter or something somewhere inline to keep this debris out
New Evaporator and expansion valve. Probably should have swapped that little switch in there too but it works fine so it stayed.
AC Amp mod. Supposedly this will disable the rpm sensing circuitry so the compressor doesnt kick in on start up or low idle. Then, by using the extra driver chip and extra capacitor in my GM PCM i can control the Idle up with the engine computer via HP Tuners by using 12v. Both of these things together SHOULD give me a stock running AC system, as it was designed to be ran.
I also decided to just use the Silverado gas pedal, as it was matching to the Tac module that came from the donor truck and it was all matching. Seems like other folks use car pedals for the positioning but with some "mods" the Silverado pedal works and fits just fine in there. Also, this was included with my motor so i didnt have to spend any more money. I just traced out the land cruiser mounting bracket onto some cardboard and made the one usable mounting hole on the silverado pedal line up with the left mounting hole on the LC template.
I basically cut the entire bottom off of the bracket, then recycled one of the mounting tabs from it. Then I made it oblong to give me some adjustability in mounting it to the firewall. On the side of the Silverado pedal, I ground down a groove for the tab to ride in and welded it in.
I forgot to take pictures of this, but i just cut off the majority of the Silverado pedal arm. Then cut off the LC pedal about an inch after it gets straight towards the top. I threw down some welding blanket on my floor and mounted the new hacked up pedal to the firewall and tacked in the land cruiser pedal to the new bracket. After verifying it was in a good location i took it all off and burned it in. Probably should have cleaned the material a little better but whatever it works. No one will see the welds and its going to be painted black.
