Guys need some help What is this hole....it looks factory what covers it...is it a water outlet...looks like water will go straight inside
A better picture is needed, although I just took some pictures of mine and have a hole (no wise cracks) that has a factory plug in it and is about where I think you show your's a second one is also factory inboard and forward of the first and about above heater opening. Look in the Danchuk book under grommets for that plug. I have an assembly manual I would have to dig it up. If you are building or just own a 57 I would recommend buying both manuals, service and assymbly. Pat
The OP is pointing to a rust hole in the corner. His radio antenna hole is welded shut. @1934coupe has sound advice.
Thanks for the advice guys....it doesn't look like a rust hole...I did weld the antenna hole shut ....I might just weld it in
It looks like there has been some firewall/cowl/air box work done; my guess is it's just part of the work that was done, and not sealed up. I am Butch/56sedandelivery.
I'm assuming that's short for "acken-puckie"? You could also glue a piece over the hole using a blob of "poly pecker".
