Plumbing non stock belkamp heater/defroster.

The heater in my 725, was not original. It is a belkamp model. It’s a small 13k btu model. To make a long process short, summit racing has a 2.5 diameter hose set for sale, total should be around 40$. I ordered the 7x.5 model, although the duct length is longer in the 725, it works. The one thing summit doesn’t offer is a way to attach it to the belkamp. That can be found at
https://nostalgicac.com/defrost-difu...sh-grille.html. They have an adapter that works for a 2” hole.the also have all the products needed to ramp up to the 2.5 for the ducts.
Anyway, it all bolts, screws, zip ties in fast, and works

Cool. Good info. Thanks.
