Transmission crossmember Install issues

[R.O.B.]

Ok, I'm converting from 4spd manual to 700r4. Finally got torque converter issues worked out and the tranny is mounted to the engine. I bought POL TCM6372 transmission crossmember, the kind that has upper and lower mounts. Apparently only Brothers truck sells this style. Anyway, of course I will have to drill new holes, just my luck. But my real problem is with a brand new tranny mount, if I rest the mount onto the crossmember, the engine is tilted to far down. It's like I need a 2 inch spacer between the tranny mount and crossmember to level off better. What's wrong here?
