Do you have pics posted anywhere? I'd rather do a side mount. I see the RCM sells a couple mounts for Hyper and Jammin but I don't know if the bolt pattern matches the OFNA LX..
I have pics somewhere but they are on a usb drive and I'm not sure where that is. If I find it I will post them. As far as the holes lining up from different models... not sure. You could go pull up the manuals from ofnas website and compare part numbers, I know they use alot of the same parts on different vehicles and maybe they use the same rear support for the center diff on something else.
I have sent my OFNA GTP Center diff to Mike to be used as a template and he is making a brushless motorplate. Hopefully he will make it available to all that want one. It seems like a popular conversion..
