I have a 230 Inline 6 along with the original 4 speed transmission that I'll be installing back into a 65 C10 project. The bell housing cross member is off too. I'm thinking the best way is to:

1. Install bell housing cross member
2. Bolt Bell housing & clutch to motor.
3. Drop motor and bell housing in and bolt up
4. Install transmission last.

Please let me know if there's an easier way. Thanks....
