I have a 1988 2wd sapphire cosworth. Will standard 3 dr. cosworth alloy wheels or standard rs500 alloy wheels and tyres fit this car? What size are wheels and tyres?

Does standard 3 dr. cosworth alloy wheels and standard rs500 alloy wheels have the same pcd and tyre size?

Does anybody have any pictures of those alloy wheels on a sapphire cosworth.
