the manual I have specifies to put the gear stack in two gears at once but not by using the shift lever, you would somehow do this with the top cover off.
luckily for me, the driveshaft has a carrier bearing so I'd only need to modify half of it at this point. Eventually the rear end will get swapped out so I'll need to do the other half at that point. I just want the thing mobile so I can move it without a chain and another truck.
I tried to get it to move while it was in 3rd and it just wouldn't budge.. I think that missing tooth found it's way to a place that it really shouldn't be. I'm tempted to put the cover back on it and try to run it without the drive shaft just to see what happens but I don't want to do any more damage than what has already been done..
