suregrip clutch type rebuild or not

[doug428]

I am rebuilding a clucth type suregrip that has broken gears. Dr.Diff has a replacement gear kit with all the gears for $175
but the carrier case has four of the alignment tabs broken off around the outside perimeter. will it still be ok to run.

At my place, that would be known as scrap metal.
