Got above the garage tonight and what I had for rear calipers. I've got 1 1/2 that you could make 3/4 out of, I think, lol. The one that came on my X I had to cut off, so the caliper itself is useless, but the banjo bolt and pad pins are good. I bought the other one just to rob the e-brake arm off it, so I can't verify the caliper works but if it does the pieces would be there for a working caliper minus the e-brake arm. Here are some pics.
Now that I think about it, I might have an e-brake arm that could be made to work . . . I'll try to get out there and look again tomorrow. If you think you could use them, you could have them.
