Overview
Rubber Insulators
All of the following insultors are interchangeable — they fit any year 1200.
11223-H1000 INSULATOR-engine mounting, front [8 mm studs] $12.70 USD 11223-H5000 INSULATOR-ENGINE MOUNTING, FRONT 7510-8503 [8mm studs] 11223-G1900 INSULATOR-ENGINE MOUNTING, FRONT 8504- [8mm studs]
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
As you can see these Datsun 1000 parts are different from newer (B110, etc) mounts.
11223-18001 INSULATOR-engine mounting front
POST qik1000 used Ford Laser mountsCustom engine mounts to suit A14/A15. I used new ford laser upper engine mounts, which are significantly larger/stiffer than the originals. This eliminates axle tramp.
1985-1990 BD/BF Mazda 323, KA/KB Ford Laser Rear Engine Mount (spacing varies from B10 mount)
11121-18000 BRACKET-engine mounting front (R.H.) * stepped bracket - looks similar to B110 LH bracket 11122-18000 BRACKET-engine mounting front (L.H.) * flat (unstepped) bracket
RH stepped bracket

B210 Mounts

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
Left and Right together
Upgraded Insulators
Puck Type
Many favor puck-style insulators, because they are readily available in polyurethane, although OEM-style new rubber makes for less vibration. Either style insulator (stock or puck) can fit stock L-type or A-type mounts.
Universal puck-style mounts, in rubber or polyurethane
These are the heavy duty engine mounts we were talking about. Broken engine mounts are a common thing in rally cars and this fixes the problem. Mounts are polyurethane and come out of a ford cortina and last for years of competition...Part number MT8156N. Kelpro make them...I usually just go to a good parts place and ask for cortina engine mounts and this is what they give me. Maybe there are two types, these are about 70mm in dia.
quote: you might want to look at the poly-urathene style mounts. I am using some of a Jag. The part number is at home. but they are heaps wider but no tallers, so they make a good direct replacement, plus they are high temp rated.
Maddat Product No - REM1200F Polyurethane Engine Mounts. Suit 1200 Reversed engine X-member (pair). New revised editions have stainless steel plates and increased re-enforcement with a slightly softer compound.
