Putting in a new defroster hose. 84 CJ-7

Am I missing something. This has got me frustrated to no end. I cannot get the new hose to fit and stay. The aftermarket hose's plastic clamps will not close and stay on. Has anyone else faced this problem and what did you do about it?

Thanks

I am about to replace this on my 84 as well, as soon as it gets here, should be any day now. If the hose clamps they provide don't work, I have some big ol' tie straps that i will use. That and some duct tape and you should be good to go

I bought one from quadratec,same issue you have. Either end looked the same size,finally got it on the top section and clamped,the bottom clamp ripped off the hose and at that point I gave up on it. Its shoved far enough on the ducts it hasent come undown yet but it still pisses me off. If every part I had to replace on my Jeep was like this Id douse the bastage and gas and light it up.

I bought one from 4wd.com and had the same issue. I used a heat gun set on low and lightly heated one end at a time. I put the top end on with the duct out of the jeep. Then I put the other end on the heater box, then mounted the duct. It was a PITA, and I did split the tube on one end, but it split where it is on the duct, so no air leak. It was tough, and frustrating, but doable. Plus, the duct and heater box had 2 small tabs that you slide the tube over before clamping so it won't come off. And I hate duct tape for permanent repairs. Sooner or later you have to go back and reapply the tape or fix it right and I hate doing things twice.

I remember it being a PITA but it ended up going on. Its been over a year and still there with no problems. I'm not sure if this will help but when I put mine on I had the heater blasting to keep warm ( I did this in the middle of winter). The heat probably helped stretch the plastic.

Same problem here but I used aluminum foil duct tape. Having been in the HVAC industry for years this stuff works great as a permanent duct closure tape. This can be found in any store like Home Depot or Lowes in the duct isle.

Same problem here. Seems the hose is a tad to small to slip over the duct and get it to clamp shut. I ended up braking the clamp on one end it was so tight. I finally gave up and just used some zip ties.

I believe that the zip tie thing is the way I'm going. I'll post later to let y'all know how it worked.
Thanks

If we're talking about the flexible duct from the HVAC box to the plactic defroster nozzle in the cowl, don't they still sell those at the dealer? I have a couple NOS Mopar pieces in the garage that I got a couple year ago.
