The JB/JD7 calipers were an option on the C20 and K20's. Year wise, I do know they were available in the mid to late 80's, but I do not know for sure on just other years they were available.

The '76-'78 Eldorado calipers technically are not a D52 designation, but they are the same physical size and shape, and with the same 7.062" center to center measurement on the mounting bolts, as the D52 calipers. The D154 calipers were used from '79 and up and are smaller, with a shorter mounting bolt dimension.
