G'day all, The factory gauges come up on ebay reasonably often. I purchased a set with all of the adaptors in the original wooden box for $US40. As Owen mentioned the wear on the gearbox shafts can nullify the benefit of new bushes. NOS output shafts do come up on ebay and i purchased a NOS 55 Twin Ultra shaft on ebay for $US 35 about six months ago. To grind, hard chrome and resize the shaft costs around $US110. The large converter seal at the transmission is very rarely at fault as it handles only exhaust oils. The culprit is either the converter ring seal or the loosening of the 6 screws holding the converter hub drive. The converter hub is very sensitive to imbalance caused by reconditioners not adequately marking the original balancing on converter items. I have made up most of the specialist tools for the trans overhaul and I shall post details when i get a chance. Best regards Peter Toet
