Grigg,
I had a question about best ways to go as I was reading your tech tip on the 4BT swap where your cut 10” out of a P30 to use it on that build. Would that be a reasonable way to go since I want to convert my 1.5 ton 4400 to disc brakes. I don’t have a 2 ton axle, so I was just thinking of finding a 5/10 front and rear combo and do the cut down and weld. Otherwise if I use the methods you described earlier in this thread I would have to source a 2 ton axle as well as the 5/10 P30 axle correct?
