I was replacing front brakes and calipers on my 2004 grand caravan and had them removed, the calipers came with new slide pins, i removed them and didnt realize they were two different sizes 1 shorter than the other can anyone tell me which one is the upper and which is the lower. they fit both holes the same neither one bottoms out.

 

Can't be possitive but I don't think they are supposed to be different lengths.
