Got a dana 50 SD front axle that has been narrowed for a good price. Seems like a pretty old school build because it was setup to run 8x6.5 spacers and sit at around 62.5" wms to wms if i remember right. I was curious if anyone has a repository of information about factory rear axles that are 8x6.5 that are of similar enough width to run. The rig in question is an 86 b2 that i have ran a d30/8.8 under for a long time and it works great but i wanna get some 40s on it. I like the narrow width it has its really good in the narrow forests in the pnw.
