I went in the garage and dug up the original output drives of my Ofna diffs and you are correct in saying that 0.229'' is wrong. I gave you that info and I'm sorry. I measured 0.190'' and that is from the original output drives of the diffs, not some bogus calculations from CAD drawings like I gave before. When putting the original output drives in the gear, they do stick out a little bit but definitely not as much as your pic shows. The part that sticks out on the OFNA drive I measured as 0.018''. As for the total length of both of your output shafts you'll be left with after you shorten them, you will have to try them to see if the drive shafts fit without rubbing on the tranny case like you said. That machine shop with the tens of thousands of dollars, if not hundreds of thousands of dollars in equipment should invest in a 20 dollar carbide drill bit and an 80 dollar carbide M3 tap. Unbelievable that they said they can't do it. I suspect they just don't want to do it and they should be honest and just say so and explain why.
