Resto in progress: The heater box is out of my A body- I put in the new heater core and basically restored the heater box and admittedly it looks pretty damn good! However, one of the vent tubes was in pretty bad shape, the other is do-able. I tried to "restore' the bad one which was patched up by previous owners @ 15-20 years ago. All the black material has been torn from the center for about 10" so i tried to remake it carefully with duct tape but I think i may have lost about an inch of length and lost a bit of FLEX. Im open for suggestions!!!!!! What sux is the ends are tapered at different sizes, one @ 2" the other 2 1/2" . I cant find replacements at places like R/T specialties, Jacks, or SMS. Any help out there? Thanks TOM
