Whoever said a B-210 axle will bolt right in a 1200 needs to have his butt kicked! I think I was one of the ones who said it, and i got my butt kicked by it last night!
To get Gilligan ready to deliver to his new owner, I wanted to swap out the 4.11 R&P for a stock 1200 punkin. Well, turns out the two complete axles I had in storage were both B-210 units. I took the most stock one and spent an hour or two in the 117 degree Texas heat trying to fit it.
To make a short story long, the "U" bolts and lower plates are slightly different on a B-210 and the 1200 stuff wouldn't fit. I finally gave up and put in an incomplete, no brake hardware except drums, 1200 axle just to get the thing rolling again.
I'll 'splain all of it to the purchaser and offer parts to make it right. I think he's planning to use his own axle anyway. I hope so, I want my brake drums back!
