GM tranny mount (for Datsun)

[jake7140]

A Datsun expert has found that part #3.1108 is a great fit for the early Datsun roadsters.  So I went to get one and found there seem to be many suffixes in addition to the base part # (and G & R).  I ordered a 3.1108R.  This mount is a bit too tall.  Is there another mount that is 1/2" shorter but meets the other specs of thew 3.1108?  http://www.energysuspension.com/media2/gm_t_mt.jpg

Overall height would be about 1-7/16".  Since some fab will be needed anyway, the crossmember-side holes could be further apart.

Thanks

I can appreciate your creativity when approaching a solution such as this, but unfortunately this specific mount is only available in one height. 
I wish you well in your project none the less.
