Losi XXX-CR Front Hex stub axles

[AmiSMB]

I have bought some nearly new Losi front 2wd wheels with tyres and so I have decided to modify my X-6 with the B4 front end to allow them to be used. I am using the following parts:-

A-1122 Front Spindle and carrier
A-1133 Front hex stubs and screws
A-3016 Axle spacer

I have looked at the manual and exploded parts view from the Losi website and cannot believe that the hex stub does not reach the inside of the inner bearing. Also I cannot believe the use of the axle spacer as the whole construction just seems to be a bit of a bodge to me. Can anyone who has any experience with the front end on a CR tell me if this is correct?
