This kit is for 93-96:

Neither one specifies aluminum or iron. I would think that they would need 2 different rebuild kits. I have aluminum calipers that came off of a 90 but they could easily be from a 93-96 car originally and I wouldn't know the difference. Anyone know which I should order?

Anyone know?

93~96 is Iron
90~ 92 is Aluminum

Since yours is aluminum get the 90~92 kit.

Is there really a difference?
