I am looking to rebuild my calipers after I powder coat them. Tried to go to autozone and they couldn't firgue it out . Does anyone know the stock bore seal size? If so does anyone also know the rear?

I don't know the size, but here are the rebuild part numbers. This includes pistons.
Front - 5017842AB
Rear - 50119488A

If you want just the seals, try these:
Front: D351458
Rear: D351962

Front is shared with the RSX, 58mm I believe. At least that's what it used to be listed as in a parts lookup. Now it's listed as a 2.125 in for the front and 1.3281 in for the rear.

Looks like they've fixed a lot of this over the years as I've always had to resort to getting reman calipers as the rebuild kits were never right.
