Very nice to see this back-room gear trading going on! <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />
Well to bring closure to my end of the story: car's back home... finally... sheesh. At least the wait - accompanied by a giant sucking sound coming from the direction of my checking account <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" /> - has resulted in: no whine - snappy shifting - and one less thing to worry about.
I ended up with new syncros, new fifth AND sixth gears, new guards diff, new differential bearings, new pinion bearings, case seals, and spot welding leaky tranny case from busted diff parts being thrown around inside. The IMA men musta had the tranny in and out four times diagnosing each problem in turn: bad quaife diff (that part was obvious - and the source of much of the other mayhem), perfecting pinion backlash (a shop-fabricated shim was required to get it right - porsche didn't offer the size needed), the high-gear issues that didn't really get noticed until the car was driven at speed.
My tiny 968 rebuild got sidelined by the mr. moneybags drive-by-wire paddle-shifting 911 turbo monster cost-is-no-object racecar project - Chris will never again promise a four-day(!) pinion-job turnaround <img src="/forum/images/smilies/968/tongue.gif" class="smilie" alt="" /> - but - and I know I'm rationalizing here - I'd rather take the car to a shop that gets those kind of projects... even if it takes a bit... er exponentially.... longer.
