These do not come around often if at all .If you need one take a look. https://www.ebay.com/itm/112834705677?ssPageName=STRK:MESELX:IT&_trksid=p3984.m1555.l2649
WoW!! I would think that this would be a very rare piece. I don't think I ever considered the fact that a Cobra would have a heater.
Since I already have had multiple inquiries about this unit from more than one country, I will add to Bob's description.
Cobras before CS 2030 did not have cockpit heater windscreen demisters. Bob has the main unit with heat exchanger core, electric fan (Bob will have to tell us if the fan blade in there), and the two often missing windscreen duct molded rubber elbows. The version Bob has offered is for CSX2031 through CSX2200 chassis.
Not included is the semi-flex round duct hoses, the under cowl funnel shaped diffusers, the formed aluminum deflectors that mount behind the windscreen over the diffusers, the dash mounted fan control switch assembly, or any mounting ancillary parts or fasteners.
