need pics of bare non-ac cab - The 1947 - Present Chevrolet & GMC Truck Message Board Network

*1FaastC10* · 06-24-2004, 09:59 PM

i removed the AC from my 86 tonight, and started to do the install on the heater box. i noticed that the hole where the AC heater hoses go will be covered by the non-ac box, this area will be used as the inlet to the heater core. the existing hole for the ac heater core will be covered with diamond plate. i need a general idea of how big the inlet needs to be cut, and a basic idea of where the heater hoses will exit the cab. any help you can provide is appreciated.

thanks for your help guys! now i've got an idea of where i need to put the holes for the hoses in the one blockoff plate. the only thing that worries me is the hole that is hidden in both pics (by the box in Russell's pic, and by the white plate in El Gracho's). anybody got pics of that?

my creative/resourceful side got the better of me. i found a piece of polished aluminum diamond plate that was intended for the tailgate of my 65 ElCamino, but never made it there. i cut a 9 x 12 piece and contoured it to fit the flat spots on the firewall and cover all of the unneeded holes. then i got inside the cab, traced the outline of the hole where the heater core tubes come out, then removed the plate, and installed the inside heater box. i then measured where the tubes come out, reversed the measurements and cut holes out of the plate. a good bead of silicone around the whole mess, and bolted/screwed it in place to cure. its not the prettiest, but neither is the whole truck, so im not worried about it in the least.
