what do you guys think about using small pieces of fuel tubing in the place of o-rings in the front diff cups of an MT2. there is too much play in the dogbone diff cup, when the wheels turn the outside ball of the dogbone comes partially out of the wheel-cup and it is damaging. sometimes the dogbone comes out all together. what I wanna do is cut a piece of fuel tube that is a little bigger than the o-ring to make the dogbone have a snug fit....not too tight, but tight enough to hold it in there.
