Which type caliper...Slider or pin?

Had same issue with pin mount calipers.
Swapping side to side does not solve.

Yeah, because some years of the pin calipers have the hose in the wrong spot for A bodies. The pin style calipers will work, but only certain versions of the calipers. @hemi71x would know...
