S 10 Caliper question

[p38fighter]

1959 convertible

In reading through the various disc brake conversion threads and looking at the parts list in the resource center I saw a comment that the 2WD caliper had the banjo port in a better position than the 4WD unit. However I haven't been able to discern the parts # for that 2 WD caliper. Has anyone got it?
Thanks as usual...
