Vintage Air Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

lts70 · 05-14-2008, 09:49 PM

I am installing a sure-fit system in my truck with a universal coil that will allow me to shave my fire wall and run a 4-way bulkhead for my lines. I found a couple trucks on the board that I really like and would like to do the same thing. These trucks have the bulkhead running through the original blower motor location. To do this I need to cut through the inner cowl vent area, I will attach an aproximate location. I will also attach pictures of the trucks that inspired me And my newly shaved fire wall.

Does anyone know if I need to do anything special to go this route? Like to prevent water from leaking from the cowl. Any advice on how to do this modification the right way would be greatly appreciated. Thanks Guys.

The black box marks the area I think I will have to cut through.

With the Vintage air set up I will be blocking of my fresh air vent on my passenger side for good. So I wonder if I should just totally seal off that side of the cowl to prevent any leakage. Any Ideas? I am at a stand still until I figure this one out and I don’t just want to dive in and start cutting up my cab with out knowing how to seal it up or know if it even will be a problem in that area.

Here's two pictures of my truck, one is before I cut the firewall and one after.
I don't like the fact I cut it the way I did but I could not find a better place. I will shave the cowl not because I may have ruined the water drain area of the fresh air vent. It dosen't leak now but I don't want to take any chances.

Its70, if you have any questions about my install PM me!

Thanks fastom for the great pics. I sent you a PM.

Does any one have any sugesstions on how they would punch through this area of the cab and how they would address sealing it back up afterwards. I am thinking I can use patch plates to close the gaps around the hoses down and then use alot of sealant or I could seal off the cowl above some how.
