MckinneyMotorsports.com and tophatperformance.com both have direct bolt in engine mounts. The Mckinney mounts are nicer but the Top Hat mounts are cheaper. Mckinney offers a driveshaft but I think you can have one made locally for quite a bit cheaper.
You can also send the RB harness and the 240 harness to Mckinney and for about $350 they will send you back a direct plug in harness.
