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.

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.
