Front hub selection question

[craig113]

I have been looking into a lot of post between here and Pirate. Or make asking the wrong search questions.

84 Chevy K30 CC Fleet side 454 T400 205
85 Front Dana 60
84 Rear 14 corp FF

I am going to be doing a bit of towing and figure that a dually rear end will keep it on the road better. Found another 84 CC C30 dually.

?? Be then... rear is easy, drop the Dana 70 in the rear and swap the bed.

As for the fronts, are the front hubs going to swap over easy for the use of the dually wheels? I see the seal and bearing are all the same, but will the manual locking hub system still work with the C30 setup or do I have to purchase a new hub?
I see that the C30 has a dust cap for the bearing, if center boar is not large enough for the K30 axle setup can I just turn it in a lathe and open it up to allow for the manual locking hubs.
