Do you have a pic of what the mount looks like?
Can you put the dish on the mount up-side-down?
I did exactly this with my Primestar dish /
SG2100 and it worked out great.
The only side effect is that the dish elevation scale is worthless... but who cares. You set the motor elevation, USALS to the TS sat (or zero it if you are so lucky), and dial in the dish elevation as needed.
