question about gears

[bigjohnson4.6gt]

i cancelled my order from 50resto.com cause it was taking too long, i was looking on american muscle and was wondering if i would need a master bearing kit with this package http://www.americanmuscle.com/speedcal-410-gear-oil-kit.html

It's always a good idea to change the bearings while doing gears.. It's just cheap insurance..

would the motive bearing kit work with frpp gear kit?
