I cant find her dimples

[tphsmith]

I have been trying, looking, searching, and getting no where. I am working on a big jig saw puzzle 72 swb. Im changing my non A/C cab to A/C. a few guys have posted a guide on here where to cut the fire wall for the blower and evaporator asm. and I have also been told there will be dimples in the plenum for the location of the air shut off valve. well to this point. this area has been repaired with a new peice of sheet metal because it had rusted out. now after that was done a few years ago. now I want to make the cab a/c. so the dimples are gone. my cab has lost the dimples. can anyone PLEASE post some pics of the location of the air shut off valve like maybe a few when they were reassembling the system to the firewall. or is there anyway some one can measure the location where the three holes need to be from a refrence of the hole in the plenum where the corner of the evap and blower assembly mounts to the firewall near the three holes I need to drill in the wall or other form of refrence point. (the wife says she'll buy someone a 12 pack.its worth a 12 pack to anyone who can help, she cant stand my frustration on this issue with the truck). and to close for now just a bit more, I need to find a few parts for this also in the assembly manual it shows a few parts I dont have. I have bought 3 units now that have come off the trucks and I still am not getting all the parts. I need the cover that supports the three holes and the actuator assembly and hardware for the air shut off valve thanks for reading and I sure hope someone can help me out
