I currently have an 85 rear axle under my truck, I also have another 83 rear axle complete, and I also have a 86 axle complete.
Should I use the 83 for spare parts for my 85, or swap in the 86 and have no spare parts.....that would leave me with 2 axles that I couldn't use.
The 86 would be nice, but already having extra parts for my current sounds nicer.
