Bad news. I was only able to have one set of pins made, reason being the company who I ordered the 4340 HTSR steel from sent me tool steel instead (the wrong stuff). I phoned around desperately trying to find some 4340, but nobody had the right size. In the end, the machine shop ended up having to fab the pins from much larger chunks of 4340 steel they had lying around and as a result the price came up significantly ($145).
The good news is that the pins fit like a glove.

The aren't press fit, but they are the closest thing to press fit. I figured this would make the install easier. They take up all of the slop and now my VCU/planetary combo is solid and has no play.
I'll post pics once I find my camera sync cable and I'll let you guys know if they actually fix my clunk if I ever get my transaxle together again.... as I suffered a bit of a minor set back this evening. When I went to put the transaxle end cover back on, I snapped the plastic "appendage" of the oil guide on the end cover. I guess this is what happens with 17 year old plastic.

Now I'm going to have wait 2-3 weeks until I can get a new one. Anybody know where I can find an oil guide that can be couriered here ASAP?
