Bulge Under Cowl

[Steve_69]

On my 68, I am cleaning and stripping paint for prep and working on the front under the windshield. Under the cowl grill, on the passenger's side, there is a bulge area that is open from under the dash. I do not remember anything fitting up inside it. Can anyone tell me what this bulge is for? It was over 2 years ago when I removed the dash and other components and I have slept since then. Thanks, Steve

Sounds like you are describing the air inlet for the heater. It has a cap on it to let air in but not water. On late cars the heater buts up to it with a gasket on the inside-no fitting like the early cars. Hope this helps.

Thanks JT. I believe you are spot on. I am debating about removing the cowl to do refurbishment underneath, but some of the welding around the windshield frame looks difficult to remove and put back. Struggling mentally. Hate to get into something beyond my skill level.
