Anybody no where to find the connectors that go between the duct assembly and the cowl. see page 51 of the factory assembly manual.

does anyone have an idea of what else could be used for this.

thanks in advance

I don't have the assembly manual handy, but what I believe you are talking about is available at restoration world and classic industries. Restoration world had the best price I could find. They were easy to work with as well. Their website is http://www.parts123.com/PartFrame.asp?ZTM=cadeflbb&GHOME=www.chevroletrestorationworld.com/catalog.htm&TITLE=RESTORATION_WORLD
If you don't find what you are looking for on their website, just call them. They are very helpful in finding you the right parts.
