Fitting the B44 hexes is going to be a challenge as there is no direct fit part for the front. The rear you can use if you drill out the 12mm hexes and space them correctly.

The 6 degree caster blocks are an option if adjusting caster at the hub side, however the front kickup is adjustable to give similar results.
