they may fit and they may not.. i see you have SD headers so not sure if they will clear the firewall or not. i tried to install the shorter dog bones a while back and my Pacesetters did not clear so i couldn't pull the engine forward enough to install them, as for using them with poly mounts i dont see any issue with that.

alternative would be like Bio said and just get engine and trans spacers to raise the engine up a little bit.
