will disco hubs fit RRC axle?

A while back I fitted a RRC rear axle to my defender to benefit from disc brakes. However when I changed all the running gear over the 5 bolts for the RRC drive flanges were missing so I used my defender bolts which were totally wrong and trashed all the threads. Im just wondering if a disco 1 hub assembly would fit the RRC axle and are the front and rears different?

Cheers in advance

if of a similar age early hubs are unf and will interchange ,later are metric of which there are 2 thicknesses, later been thinner and having shorter stub axle and thinner drive members
