Bolt it in. Might need to shim. I didn't, nor did I see if it needed, but also haven't wheeled mine much.

Make sure to use new c-clips for the front shafts. There are past discussions with some who have had the shafts pop out under full drop. No clear understanding of what was happening. Kevin C had som egood thoughts on it. IIRC, some that experienced it reused their c-clips. No one had problems other than under tougher wheeling conditions, as i recall.
