Contacted Jim this morning. He says the chopper-wheel and pickup are not fabricated to fit early e3's but they do work on euro 323's and the like. Possibly there is someone out there who has used the later engine with an autobox. Next stop, seniorsix.org Thanks anyway. You are NOT "out of luck." Contact Jim Rowe of Metric Mechanics, he offers the chopper-wheel and pick-up, slightly modified to mount to the earlier side-loader differential cars. You will also need to use the small e-box which a shorter replacement for your speedo cable goes into. A little wiring, and voila' !
