Guess I'll put it here as this is, at least to this old buzzard, the path of least resistance After almost 190,000 miles and a bit of bearing noise I decided to give the 5 speed in my 78 280 the business and @ the same time address all of the related issues. At the risk of glazing the eyes of my audience I promise to be brief. I had the rear engine plate powder coated - yes, I know it was clear zinc plated from the factory but I wanted to see what my very excellent powder coater could do and the results are very satisfactory - removed 4 pounds from the stock 24 pound flywheel, had the now lightened flywheel balanced along with a new pressure plate, replaced the rear engine seal, clutch assy - used the Exedy set for probably the 100th + time in my career - flywheel and pressure plate fasteners, ALL of the trans bearings, 2nd and 3rd gear syncros, seals and gasket and had all of the related fasteners, etc. zinc replated. This past Sat I drove the 350 mile round trip to Import Carlisle - touched 100 MPH for a couple of seconds - without a hint of concern. I got those trans parts I could from Nissan - yes, I know there are some cheaper alternatives but I like the guys at my fav dealer. Those bearings that are NLA from Nissan I got from a company in Japan, Amayma. They, Amayma, provide excellent service and excellent prices for parts in the original Nissan packaging. Way back in 1971 the dealer I was working for sent me to Datsun trans school. The school held @ Datsun eastern headquarters in Secaucus, NJ. The dealer provided me with a NEW, just off the boat, 510 2 door for transportation. Yes, a new 510 2 door was capable of an indicated 100+. We were provided lunch at what was, I'm confident, a mob owned restaurant. Our instructor told us we could order ANYTHING on the menu but if we wanted lobster we had to give one day notice. Those were the days.
