I'm not quite sure what your asking as you only mentioned model 2 bases,but I'm thinking you are asking about the axle brackets that are welded to the base.If so there were two different's in the thickness of these brackets.That was on the Model 1 Rotomo's,but not all of those and I believe the model 3 had the same as well,but again I'm not sure they all did.As I was told (So may not be fact) that Victa had two manufactures of those bases.If that's not what you were asking then sorry.I just didn't fully understand.

Here for a good time,not a long time.
