Plastic flange 8 screw holes for 1989 Prostar 190

[jonathanwsmith]

I need to replace both exhaust flanges. you cannot tighten the clamp around a new exhaust hose if the flange is warped. I ordered two flanges from skidim but apparently theirs has 6 screw holes and I need 8. As I'm not eager to "fill" 16 old holes and drill 12 new ones, does anyone know a source for the original equipment?

Thanks,
