Great info guys...Thanks!

I decided to order the center shaft and C clips from Ford. Not expensive and figured 'worth it'. Local parts guy does not beat me up with retail. Did not know about the sponsors but will check in future.

Will pull and inspect axles today...hopefully they will be OK.
Will have to add O rings as well.

After 'assembled'....check play (any tricks?) or just figure existing shims should provide right spacing?

Anything else to inspect prior to buttoning it up?

This has been a 'challenge' (read PITA) but considering the cost of 'just paying to have it done', well worth the trouble. Besides, I know if I do my own wrenching, it might take longer but will be right.
Thanks again .....forum has been GREAT help.
