OK, so Im getting ready to repair years of holes cut and drilled in my firewall. What I really need is pics of the way different A/C units exit the firewall. I am undecided as to which unit I will use, so if I can see how they all mount, it will keep me from having to redrill holes that I have already filled.
Thanks ahead of time for any help,

 

Jeff,
I pondered the same thing when I started filling holes. In the end, I filled in everything and figured I'd be able to drill holes where I wanted, when I wanted.

There are several bulkheads for firewall pass throughs. Did you see 49willard's recent post about routing his hoses? those bulkead connectors looked very nice. Checkout AXracer's gallery, about a year or so ago he had a posting about making a really cool stainless cover for a similar bulkead connector. I believe he used a stainless steel dog dish as a cover.

I'm in the process of filling the holes in mine to. I'm going to fill all 100 or so maybe not that many but you get the idea. And make my own when and as I need them. But not very many I want mine smooth. ............Rusty

 

I started to fill mine but discovered mid fifty sell a sheet metal facing.
bought one tacked it in place much easier looks nice.

 

Thanks all, I think I'll fill them all as Bobby suggested and start from scratch.

I checked out the galleries and like the routing in 49willards truck, all of those hoses sticking out in the open on Axracer's "Gracie" are rather "fugly" as Chuck would say.
