Question What brand exhaust diverters did Sonic use??

I'm trying to figure out what brand my exhaust diverters are on my 94 31ss 454 mags. I would like to replace the rubbers on the exhaust diverter flappers as they tend to clang a little. I can't find a name brand on them anywhere. Anyone know if these are corsa? Other brand? Where can I get the replacement rubbers and hinge pins???

I'll try to get a pic today and send to you... I found the parts on the imco site, I'm thinking that it looks like a standard part. I'm also taking the boat in to have a coupler replaced, going to ask if they can get the parts as well.

Not electric, looks like the trim pumps setup, not sure if it's air or fluid, I'll check it out closer. The Y pipe diverters are black, not polished and no manufacturer markings, though there are some numbers on them.

It's an air pump setup.

also note! if its the flapper on the y pipe it takes four. they did away with the steel rod that holds the flap and now use a molded plastic press in.the old part#14348A1 they will give you the #.
