Anyone know of a parts interchange book or online source.

I am wanting to know what parts of the car are shared with other GM vehicles

yeah I need to know if any rotors interchange cause they cost like 70 each its stupid I never have paid over $25 for a brand new rotor and no they can't be turned thats why I need new ones.

Some Cadillac rotors fit the Aurora's. You paying 70 bucks for front ones? That is x-pensive I just put rear ones on my car and got them for 10 bucks a
piece. As far as the fronts I've been lucky and have come across a few used ones turned them and I'm set.

I have a '96' and I got 4 new rotors at advance auto for under $40 I have the smaller rotor though.
I think half year 96 they changed to a bigger rotor. those were like $30 a piece at advance. I know cause they gave the wrong ones at first

Be careful with those CHINA rotors! Cost isn't everything.

I can't' find them that cheap at all so it sucks I've tried everywhere.

partsamerica.com, which sells for CSK and Advance stores, has Raybestos Raymold's for $24.99 ea.
