1989 gta, single or dual piston caliper?

cant tell. bought pads for dual piston, thinking mine looks more like a single piston. cant find specs anywhere. thinking it should be 2 piston on a gta. car is getting rained on too much right now to go underneath and check.

edit, talking about fronts right now. might as well find out about the rears now while im at it.

Fronts are iron Delco-Moraine calipers with single piston (only the 1LE cars were equipped with dual piston calipers). If you have rear discs, they'll be alum PBRs with single piston.
