Well after working 12 hours i stayed late at work and finally got these babies made. Cost to me was nothing other than my time so it's a pretty good deal. The finish is bad because they were test fitted several times in the differential bores and it is a slight press fit (.0008 in). At this time i have no plans to make any more, and I'm waiting on Z1 to ship me my F'ing stub shaft before i will be able to drive the car again. After i get the testing done i will decide whether or not to continue replacing more rubber including the sub-frame mounts (would be delrin) and the rear differential mount (steel insert in aluminum).
