My dad recently bought a 1993 G20 conversion van that has ABS and the backing plates are basically non existing and finding parts for it here in Canada isn't exactly easy at least where I live.

A local scrap yard told us that during covid all they crushed these vans because no one was buying parts off them.

Is there any other GM products I can get ABS backing plates off of that will fit?

I found Dorman 970-337 but it's for a Chevrolet C1500 Suburban and other models but doesn't show anything for the G20.

Any help would be great.
