I am pretty sure I know this. Are the gears in the upper or lower part of the drive? I have seen people advertise lowers for sale with a 1.50 drive ratio. If there are 1.50 gears in the lower, common sense would say get an upper with 1.50 gears to match, right? Someone slap some sense into me.

Also, how hard is it to assemble an upper and a lower if bought separately. Is there any difference in years? (Standard Bravo 1 only)

Thanks

I can't remember about the gearing for sure.

As far as putting an upper and lower together, its as simple as it looks. You just need to get a seal kit and the correct studs/bolts.
