I bought the same set from the Scarborough supplier, I had to modify the holder to fit them though. They are just a generic brand which they list them to fit every car. If you want a plug and play direct fit with no hassles, go with the Fiero Store brand. You will pay more for them but they are top quality parts and I've seen a set up close. If I had the extra cash I would have bought them instead.
As for calipers, call around your area and price out what it would cost to have yours rebuilt, compared to buying a new set. I know there are a few places in Toronto that does them. Only issues is that the car is so old, how many places still have seal kits to rebuild them in stock. Even though you just put new pads and rotors on, still look into a break upgraded. With a bigger motor now, once you have that first panic stop, you will want them right away, trust me!
Someone here with complete stock platform might buy your current set-up.
