IPSCO has been offering a mechanical spot parking brake caliper for some years, your choice of primary brake caliper.

https://www.ipsco.org/Pantera%20Parts/parkingbrakekit.htm

Many of the standalone parking brake options (and I don't have experience of them all) are based on a spot caliper that often doesn't have significant clamping force to use the parking brake as intended. Personally I think the Brits have this one down as their calipers and handbrake are required to undergo rolling road resistance testing on an annual basis for the MOT test. Hi-Spec offer integrated calipers with mechanical parking brake;

As another option for a standalone parking brake  John Haas has recently introduced a controller for Tesla electric parking brake calipers, one needs to source a pair of calipers.

Eric,

For a time, some Pantera vendors sold a complete brake kit utilizing mid-80s Corvette calipers and discs (redrilled for the Ford bolt pattern). These were single-piston sliding rear calipers with parking brake, and two-piston (Same side) sliding front calipers.

They have not been available for years, maybe decades now.

As to your specific query, sadly today the answer is ‘none’.

The next best thing is either to use the stock rear calipers with updated pads (perfectly good for street driving), or aftermarket calipers which retain the stock calipers also, to serve as a parking brake only.

A third old-school option is to fit a second set of stock calipers to each upright, effectively doubling your potential braking force at the rear. This would almost certainly destabilize the car under braking unless the stock front pressure reduction valve was removed, and an adjustable proportioning valve might be required in the rear circuit to step down the pressure to achieve the proper balance.

Of all these options, unless you are planning on extensive track driving, I would opt for stock rear calipers in proper working order fitted with Porterfield R4-S pads....
