Drefroster Duct Oval

1977 CJ5
So I ordered a Crown brand oval defroster duct and it was way too small. Said it was for 77 and up but it's not. Does anybody know where I can get the right one?

I made mine. Took 2 pieces of 4 inch clothes dryer vent, split each one up one side (and then had to trim some off each one to make them fit together) Fiddled with them a bit to make them fit together and taped with some air duct tape. It's not perfect but it works and it didn't cost a fortune. I know it sounds confusing, but I don't know how else to explain it.

I used 6 inch flex for house duct work.

I made mine too. I couldn't find one anywhere. I later read somewhere that this is it. javascript:showTank('images/airbox/CJABFAH-1_v1.jpg')

edit: that link didn't do right or I didn't do it right. Let's try again. They even have the air box, which I was told couldn't be found anywhere. Mine was also brittle and I had to patch it too. http://www.mtscompany.com/airbox.htm

It isn't available. Neither is the fuel filler hose to the gas tank. The 1977 is the dreaded red headed step child. You'll have to improvise. It has LOTS of parts unique to 1977 only. Fun, huh?

I have a few 'spares' lying around in the basement that fit the 76/77 heaters. Haven't checked them good, so there may be a few rips. The one that was in my CJ was miraculously fine:

Yeah I know all about the 77 being a red headed step child. That being said MTS now sells a fuel filler and vent hose specifically for the 77 thats a perfect fit. Put one on mine about a year ago.
