Rebuilding my gearbox, how far to go?

[milkandoj]

Im putting back together a CP5OH box i broke a selector on, 3rd was getting crunchy to so while I'm at it, I'm going to replace the "3-4 LATE hub/slider" http://www.jackstran...late-hub-slider and the 3 and 4 syncro rings. I already put steel selectors in it.

Would anyone else suggest doing more like all the bearings, they dont look scored up. I will shim it right once assembling it, asking about the parts as this stage. This box it out of my car originally so done pretty low kms.

I'm not interested in upgrading the box as its a CP5OH which is meant to be weaker than the W5M box's, if it throw $1000 worth of upgrades im thinking it may be a waste on a CP5 box. But its sitting there so i may as well use it.
I'm seriously thinking of doing the 4 spider center diff conversion as i have all the parts, and i can likely take that out if i strip the box.
All the big US gearbox builders, shep, tre, jacks, recommend them for over 400hp at the crank. Which I'm around that power figure now and looking for another reasonable 50hp in the future.

do the bearings as well..........it isnt a big cost while she is in bits and is piece of mind. bearings can look good but it doesnt take much to make them noisy as some of the damage occurs where you cant actually see it. inside the rollers

yes, check what shims the old bearings need and that will indicate how worn they are. though jack says that the input and mid shaft bearings wear the most, which is what i found with my box.
get all the seals from jack.
i should order bearings for the other box i got and split the postage with you milkand
what about the torrington for the diff?
