I am waiting for the definitive history of Triumph motor cars to come out. The one showing a picture of the guy on the production line who had 3 arms - one to hold the wheel box, one to hold the screws and one to hold the screwdriver. I have often wondered if they installed the wheel boxes BEFORE they welded up the front bulkhead! At 4 hours, you did well, Tinman.I am dealing with the wheel box's right now on my 250. Where your wiper arms attach, just underneath the sheet metal. They are a pain in the a-- to get to. I have spent about 4 hours trying to get the cable to run smooth thru the tube. That is with no dash installed.
