Oh, I see what you are saying now. Well ours may be off too then. I haven't mounted the wheelie bar on it yet. But I do have the hot racing trans case going in, so not sure if we will even be using the RPM mount at all now.
The RPM wheelie bar/bumper mount fits fine on the stock gearbox. I have seen people say it doesn't, but it went right on ours.
Great looking build man!
