Heater box alignment to ducts: BIG GAP problem

[njsteve]

FYI...the aftermarket need bent a lot to have a chance of working correctly,,,, the top is an original and the bottom is an aftermarket. Note the difference in the angle.

Thanks for the advice and the photo. The repro bracket arrived today. I bent it just like your photo and it worked perfectly the first time. I did use one of those extended claw tools to hold it in place through the gap while I got the mounting screw to engage it. This way I didn't have to pull the entire box out again. Nice and slugly mounted now.

Heater box to duct alignment on my 71. Never been apart.

I agree, my AAR is the original heater box and it has always had a gap, always wondered why, can't get it to go away so it's staying, not like it would ever really get used anyways other than as a cold air duct. As an FYI, my dash has never been out either so it came that way.
