Datsun 1200s came with two brake systems:

Drum front/drum rear - Standard trim, Deluxe trim
Disc front/drum rear - GL, GX and optional on Deluxe

The 1200 front-disc/rear-drum system was good for 1971. In fact, stopping power was better than most 'muscle cars' of the era. However, if you have a drum/drum system, you'll want to upgrade to disc/drum. The drum system stops well enough, but the disc system has less fading going down mountain roads. See Brake Swaps.

Caliper bolt spacing:

~84 mm: B110, and all 12" wheel B210 and B310
88.9 mm: B310 large struts for 13" wheels

Dia. (mm)	Part Number	Source
212.5	40206-H1006	B110, B210 with A12 1974, 1975
220 (AN18)	40206-H7500	B210 A12 1976-1978,B310 with 12" wheels
232	40206-A1155	B210 A13, PB110?, PB210 early?
245 (AN20)	40206-U6700	A10, B210 A14, B310 A14/A15, PB210 late?

Apparently the calipers are unique for each rotor, also the strut/spindle assembly *may* be different.
