The new mastercylinder arrived Monday but I need to sort out the steering before I can install it...so I ordered the $160 dunebuggy rack I was eyeing:

Its everything you'd expect at that price and more! There is quite a bit of lash and no way to adjust it but its about perfect travel wise and not the and about 1.62 turns lock to lock which I think is near prefect (they said 1.5 but that's a lie). I took it apart:

On the plus side the rack teeth are induction hardened and the pinion is hard, the bellows seem fine.
On the minus side no bushings in the housing and while it appears to be designed for a rear pinion bearing there isn't one. The rod end are 3/8" which would be only marginally adequate. And of course its mossing about 2 feet on the right side.

I stared at it for a bit trying to decide if its worth messing with...I have a plan.
1) add a rear pinion bearing
2) add rack bushings to the housing and off-set then slightly to yield a high pre load on the pinion. That will fix the lash and should it ever return replacing the bushings should again sort it but I can't imagine it will get that kind of use
3) Rethread the rack ends 12mm or maybe 1/2"
4) thread the OD on the right side of the housing
5) Add a right side rack extension
6) add a right side housing extension
I'm guessing that's $50-$100 of material then I can worry about how to install it.
