Engine Mounts
See also: Crossmember
Overview
Rubber Insulators
Engine mounting insulator sits between the engine mounting brackets and the crossmember, and provides insulation from noise and vibration.
Main: Insulators
Brackets
B110 (1970-1973) 
Late 1200 (1974-1994) + B210 + B310 
B110 and B120
Which brackets you need depend on the vehicle's crossmember.
Front: 1970-1973 1200 engine tall crossmember (B110/B120)
Rear: 1974-up 1200 tall/short engine crossmember
Not only does the new-style engine have a lower right-hand mount, but the mounts are further back 35mm (~1-3/8"). These photos shows how far back:

There are TWO types of right-side brackets:
- Top: original style
- Bottom: new style for revised crossmembers
- Allows fitment of reduction gear starters
- Starting with 1978 B210 USA (H8500)
- All B310 (H8500)
- Starting with 1985 B120 JDM (G1900)
NOTE: If you mix early engine with late crosmember (or vice-versa) it will require some modifications. In this case see A-series Engine Swaps.
Early Engine Mounting
1970-1973 Datsun 1200 uses bracket that fit the early A12 engine. Note that the left-side bracket is stepped to fit the engine block.
B110 Insulator
- 11221-H1000 BRACKET-engine mounting, front (R.H.)
- 11222-H1000 BRACKET-engine mounting, front (L.H.)
- Stepped mounting. Lower boss is farther out than upper boss
Late Engine Mounting
1974 and up engines are different, and 1974-up 1200s use a corresponding crossmember

B10 Mounts
The Datsun 1000 parts look similar to B110 mounts, but have different part numbers.
11221-18000 BRACKET-engine mounting front (R.H.) * stepped bracket - looks similar to B110 LH bracket 11222-18000 BRACKET-engine mounting front (L.H.) * flat (unstepped) bracket

Right-side mount comparison:
Middle pair is B110 early, right is B210? (thin), left is B310? (thick)
B210 crossmember change for 1978 North America
Crossmember horns are farther apart, requiring new style RH bracket
B310 uses this new spacing
B310 Mounts
The B310 insulators have a metal wrap in case the rubber breaks, the engine won't move too far.
11223-H9100 INSULATOR-ENGINE MOUNTING FRONT RH [10 mm studs] $34.38 USD 11224-H9100 INSULATOR ASSY-ENGINE MOUNTING FRONT LH $44.32 USD 
B310 insulators have a larger studs and locating pins, but otherwise are the same dimensions as B110 mounts.
11221-H8500 BRACKET-ENGINE MOUNTING, FRONT RH
Stronger, more rigid than ever - perhaps to reduce NVH (noise, vibration and harshness)
11222-H5001 BRACKET-ENGINE MOUNTING, FRONT LH
- Same as B210 and mid-model B120
