There was a minor delay due to the exchange rate, but we got it sorted and Jeff sent the parts today and gave me a tracking number. The parts are expected to arrive on the 10th (actually the 11th across the international date line). Looks like I've got to get off my duff and mod that distributor. lol

Yeah, the shaft showed up when expected but the other box should be here on Monday. The shaft looks really beautiful. I wasn't able to spend any time alone with it, but I can tell you Jeff Bruce does awesome work. It looks case hardenend and has a special woodruff type key to hold the front rotor journal in place (phase). All the other normal eccentic shaft nooks and crannies were there except the rear part has splines instead of a tapered fit for the rear counterweight.
I can't weight to see the rear counterwight and everything else. Like I said only the shaft has arrived so far. The other parts like the rotor journals should be in the other box. I'll know more tomorrow.

Here you see a front counterweight rebalanced for use in a 4 rotor arrangment, 19 long tension bolts, one long dowel pin rod and two shorter hollow dowel pins (for oil to flow through), a stationary gear machined and fit into an intermediate plate (and one below it), one front plate under the tension bolts (rear plate under it), a special rear counterweight with splines to match the splines on the end of the Jeff Bruce shaft, and finally two rotor journals that slide onto the shaft and are locked in place with a key.
The quality is superb. Jeff Bruce = class act.

In case you're wondering, Jeff Bruce didn't make that box. We did, so we could ship the side plates to Jeff. He needs the front and rear you're going to use and two intermediate plates for a 4 rotor, or one for a 3 rotor, as there are alignment issues. He dowel pins the plates together for an accurate cut to install the stationary gears into the intermediate plates. The box was made with an extra compartment large enough to ship the two new (front) stationary gears down to him. He was then able to fit the counterweights and rotor journals in there to ship back to us. I like his solution for all the tension bolts; looks like he drilled a bunch of holes in the 2x4 to secure them above the plates. 
One more thing, the rear nut is 48mm, not 54mm like what we're all used to. Makes sense since the threaded part appears to be a smaller diameter.
