heater box rebuild......the right side end of the heater box was damaged, so we decided we would disassemble the box completely, replace the damaged pieces with better pieces from a newer 73-76 box I had, and repair the pieces that would only work on the earlier 67-72 box. The section closest to the firewall, which holds the blower motor is the original housing, was separated from the center housing (9 rivets) which had too much damage. We used the center and front sections from the later housing. The pieces that were damaged were repaired with a combination of super glue and Norton 'Speedgrip" structural adhesive. After everything was fixed all of the housings were scuffed with a red scotchbrite to remove the scuffs on the housings, but not too much so as to remove the ink stampings and cast part no.s on the housings. A good coat of clear on all of the parts had them looking like new parts. then a 0000 steel wool pad was used to remove the glossy appearance on the housing, and give them more of an OEM satin finish. The repaired areas of the housing are a little darker, but since they are located on the side and back of the housings, they should never be seen. All that's now needed is to install a new heater core, the prepped blower motor, and install all new foam seals purchased from Detroit Muscle Technologies. Also one picture of one of the frame rail shields being repaired the same way. Ben.
