Ok I got new 6 lug wheels for xmas and I want to keep them. But at the same time I need to upgrade my rear end from the 10bolt. I have done some research on the 14bsf and I found that 81-87 it was available only in 8 lug but everything will bolt up under my 85 K10. Then 88-98 it was available as 6 or 8 lug but the spring perches will need to be moved. Through my research and searching on this site I have found a bunch of bits and pieces of info that I would like to put together. I believe the 14bsf never came from the factory as 6 lug and disk brakes. I am looking for a 4.10 ratio which I believe is pretty common. I would prefer if I could find (or convert) a 14bsf to 6 lug. So I do know the 8 and 6 lug axel shafts are interchangable, but then I'd run into problems with brakes. I know there are kits to convert to disk brakes, but there are all different types of spacing and axel shaft lengths which have me confused a little. Could anyone give me their 2 cents on what I need to convert a 8 lug 14bsf to 6 lug and then maybe even convert that to disk brakes? Or if not disk brakes, are the 6 and 8 lug drums directly interchangable? Also exactly what is interchangeable from the 81-87 version and the 88-98 version?
