Engine Mount (anti-vibration)

[S2e]

While I'm waiting for my Whirlwind prop, I will replace the engine mounts on my experimental S2A. The parts catalog calls for Lord J-7401-2 mounts. (I believe Aircraft Spruce calls these "Lord Elastomeric Engine Mount - Aviat.)

Does anyone have any experience with Aircraft Spruce' Special Heavy Duty Mounts? (will they even fit?)

How about Barry?
