New engine mounts for Starduster Too

[trailrunner25]

I just found 2 damaged rubber engine mounts on my Starduster Too. It has an O-360-A1a. The current mounts are Lord 7401-8. Replacing all of them is about $480 plus spacers. I see that spruce has 2 types of experimental dynafocal mounts.

Option 1 is about $250 with spacers

Option 2 is about $450 with spacers

Has anyone used either of these mounts? Does anyone know the torque spec on these?

Thanks.
