Front Crossmember
1970-1973 1200 Crossmember (two high towers)
1973-1994 1200 Crossmember (short + high towers)
Rear: Late 1200 crossmember (one short tower, one high tower)
Front: Early 1200 crossmember
The engine crossmember for the Datsun 1200 fits the 1971-1973 A12 engine. The A10 engine from the earlier Datsun 1000 will also bolt in. To fit a newer engine -- a 1974-up A12 or A13, A14 or A15 -- a newer crossmember may be used, or an modified motor mount brackets may be fabricated (see A-series Engine Swaps). The newer crossmember is from the 1974-up Datsun 1200 truck. Note that B210 or other crossmembers do not fit the 1200.
For engine types other than A-series, see: Engine Swaps
Early A12 vs. Late A12 ute (suitable for 1974-up A12, A13, A14 or A15)
Modified -- newer engine mounts sit further back on right side
B110 holes are 656 mm apart, and 60mm from each other
PB110 Crossmember
L14-powered B210 uses L-series towers and mid-sump design.
See L/Z/KA/SR_Crossmember
B210 Comparison
120Y vs B110
120Y (A12-powered B210) is slighty wider, and of course has late style mounts suitable for late A12 + A14/A15.
North American A13/A14-powered B210 has a mid-sump crossmember, almost exactly identical to the 510 crossmember. See L/Z/KA/SR_Crossmember.
Crossmember Bolting Dimensions B110 656 mm X 60mm B210 760.6 mm X 62mm(?) or 80mm(?)
