What is the difference in the two adjustable engine mounts? I have the one for Novarossi but the place I order from is out of the one for Picco.

The bolt holes for th motors are different.

If that is the case then will the mounts that come with the kit work on the picco?

The mounts that come with the kit will work on any big block crankcase.

The 2-piece engine mount option part has 2 different blocks that mount to the engine because Picco and Novarossi crankcases have different mounting holes. The blocks need to be different because they are mounting to the same fixed point on the engine mount. The stock ones just mount directly to the chassis so it doesn't matter.

Sorry to bring up this fairly old topic, but what actually is the measurement that counts? I quess it's the width, but what are the sizes?

I have few engines that are not in the "supported" list at all, for example a STS D21T. Of course i could buy both of the packages (and i most likely will at some point) but it would be nice to know what to measure to know which mount fits..
