Hemi transmission mount

[moonshine_mike]

I've read in the parts manual that a 1970 Cuda with a 426 hemi has a different transmission mount than the non Hemi.
426 Hemi transmission P/N=3410310
Non Hemi transmission P/N=2892471
Then looked at my Hemi and noticed the mount carries the 2892471 stamp which seems to be incorrect.
Does anyone know what the difference is between the two different part numbers?

good question.  I'm in for the answer.

Very confusing for my small brain but I think Hemi and six pack cats got the infamous yellow mount which I am pretty sure is part number 309? Maybe someone who has one can chime in

Not 100% positive, but I thought super trak pak cars got the yellow mount.

Just thinking out loud . . . I can't say for sure what the difference is that was ask about, but perhaps the rubber compound used on the Hemi mount has a stronger Shore hardness value . . .  or perhaps some metal reinforcement or metal stop tab was integrated into the design, should the rubber fail
