I have a heater post but this is specific for an FJ40 Front Heater Restore kit the I bought from SOR, and probably could be answered by anyone with a 74-80 FJ40 that has used it. There are 3 foam pads that obviously have to go on the internal heater doors, and then a long 29 inch long 2 7/8ths inch wide foam strip that I believe goes around the heater core. There is also another foam strip, 3/4 inch wide by 19 inch long that is the only foam that comes with a self stick side to it, at least in this kit. I have no idea where it goes and I contacted SOR and no one that was there knew either. The original metal parts for the heater are all there and in good shape, with the one possible exception, but none of the nylon grommets / pivot joints were on the heater box when I got the cruiser. I can probably work out where the nylon parts go from heater rebuild videos but that one piece of self stick foam has no obvious home to me, and I can't find instructions anywhere for this. Its probably going to be obvious but I don't want to put it all back together and find out that I should have put the foam **someplace important** and now have to take it all out again. The possible exception I mentioned is because I took all 3 screws out of the hinge rod for the upper hinge door (the one that seals off the top front vent outlet) and the plate is still solidly attached to the rod, beyond what I think just paint would do. One screw hole is really messed up on this hinge shaft but the head of that screw was broken off and I got the other 2 screws out and I wonder if the plate is soldered/brazed to the hinge/shaft since nothing mechanical should be holding the gate plate to the shaft. I will clean the plate/shaft of paint and I'll know.
