Identify J55 Calipers

[jsinga]

Does anyone know how to identify J55 calipers? I've see a pair and supposedly they are J55 calipers but they don't have any numbers I can reference. I measured the width inside from the machined surfaces, where the pads contact the outside and inside behind the pistons they measured 2 11/16 inches. The hoses attached are marked 3/95 and they are claimed to be from a 95 car.
Anyone know if these are JL9 or J55?

Thanks,

JS

Does this help?

If not, there are several other photo's here.

The bracket on the left is the original J55 bracket. The one on the right is the modified bracket which you will need for application on an 87. The link above contains a photo of the adapter plates and hardware that are also neccesary.
