The engine mounting insulators sit between the engine mounting brackets and the crossmember, and provides insulation from noise and vibration. They are designed with a particular rubber hardness, to give a balance between softness and rigidity.

B10 Mounts

As you can see these Datsun 1000 parts are different from newer (B110, etc) mounts.

POST qik1000 used Ford Laser mounts
Custom 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.

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.

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.
