So I'm working on a 77 grand prix. Built her a pretty stout 400 making about 375 hp. The fan shroud extension is busted up pretty bad as you can see by the Pic. Is this extension or a complete fan shroud available anywhere? I've also considered electric fans. The radiateo measures 28 x 18. Any recommendations? It's a non AC car

I think you could use sheet metal rivet it on and paint it black.
Or cut up another shroud and rivit it together.
My buddy has a 77 GP with a 461 alumheads with stock cluch fan and shroud and it runs 180 all the time.

This is the route I'm tentatively planning on taking. Was hoping this car shared shrouds with an older car and it was reproduced in some form though. Electric will be a last ditch choice.

I don't see a reason to go to the trouble and expense of installing electric fan(s) on your car. The factory shrouds and clutch fan should do an excellent job of cooling a 400 cubic inch motor. If your having cooling issues it's a symptom of another issue and installing electric fans would be a band-aid for another problem.

Yeah I don't want to go electric, just an option I was considering if I was unable to find a replacement or repair my existing shroud to insure proper cooling. I actually almost have it done, and i used a piece of fascia tin. I'll post a Pic tomorrow.
