if you want to go to taper roller brgs. instead of angular contact[std brgs.] drmini is right. the hubs are about .010" different in depth of brg housing. if you want i can give you some spacers to suit taper rollers to get correct pre-load on brgs. you can contact me on my email.
Often I find the hubs are worn in the centre web, then preload is non-existent and it's all sloppy with new bearings and proper spacer.
It's important that the endfloat is measured accurately and the spacer thickness reduced by the SAME amount.
The 60lb/ft torque on a drum type CV is not sufficient to allow meaningful preload- if spacer is made too thin it will be loose on assembly, when torqued up. Add a few miles and the nut will come loose and the bearings can spin and wear ther drive flange.
When torqued up 60lb/ft to test, with no seals in, there should be no bearing rock, nor any drag. Then undo and put the 2 seals in.
