1974 started as a 3.0 automatic ended up as a Motronic 3.5 with 5-speed. Amazing how many parts one could cobble from E12's, 28's and the like but that was 20 years ago! And no, wood doesn't last more than 20 years without a tune up unless it lives in a bubble. Now I do E12's. And those are getting difficult to keep looking good!
