Driven front axle options?

[WhiteWolf McBride]

This was asked of one of the axle brands, but not answered:

What about a 'throughput' front axle, like the forward unit on the dual-rear-axle semi's. Does no-one make a simple off-the-shelf unit yet, instead of us having to buy ones with metal casings at $150 and up?

I know Joe and Willy DIY'd them a while back, but isn't anyone even making a ~kit~ for those of us with minimal tools?

Only Robbe really makes one 'off-the-shelf', and I honestly don't like their axles when compared to Tamiya ones. Dislike 'em enough to ditch my 8x8 'Panther' chassis if I can do it with Tamiya parts (and they AIN'T cheap)

So, guys... is there a way for us Neanderthals?
