Anybody convert a power feed?

I have a spare ALSGS ALB-310SX horizontal power feed for my RF 30 that I'd like to convert to a vertical style 310S. Besides the mount the problem I see is the gear arrangement. My horizontal has straight cut spur gears on the motor and lead screw gear. The verticle uses bevel cut gears. So I've think I've found the bevel cut lead screw gear on eBay. But i don't see bevel cut pinion gear for the motor.

I ended up with a spare because when I put a DRO on the RF30 it was going to be a pain to mount the safety switch and I'd never ever needed it. Until a month after, yeah I know. Somehow I'd forgot to kick it in neutral and it went to end of travel and stalled, d'oh! It popped the breaker but when I reset it didn't move and after checking that it had power through the breaker I figured it was toast and got another. I wondered if a friend down the street could take a look at it and after reading the skimpy manual decided it had overheated a brush and come un soldered. Sure enough we were able to save it and it works good as new. Now I'd like to use it to power either the Z or Y axis, but need first to convert it as with the horizontal mount IMHO it would be very ungainly for either application.

Any thoughts?
 
Be careful with mixing power feeds designed for Z axis vertical feeds (mill) and X and Y axes (left, right, in, out) table feeds. I (accidentally!) installed a knee feed on the X table axis of my mill and found out that they run in opposite directions. Moved the handle left, table went right. this was an older Servo model 100, and I had to nearly completely disassemble the thing to get to the wires to the brush holders so I could reverse them to fix the problem. In my experience, you can mix X and Y drives, but not with Z drives which run the other direction.
 
Thanks. I know the handle is not clocked the same for verticle either. There are a bunch of details to this so I appreciate all input. At this point I'm still trying to figure out where to use it. But it sounds like you didn't have to change from horizontal to verticle at least. We did have it all apart to fix the brush holder so even though I'm not looking fwd to it, I've been into the guts before. It's probably a fools errand but it sux to have it just sitting.
