Tie bar pins now done and toe in adjusted, so we shall see how it goes but a road test the other day seems very promising.
New new distributor now fitted and timed up by ear !!!!!!!!!!! the old one was, well very old, so much so with the gear drive in one hand you could easily turn the rotor arm about 10 degrees from one side to the other with no resistance and not moving the gear drive, eeeek also it had variable points adjustment in that the bearing was so worn that you could wobble the shaft sideways as well and alter the gap of the points, how it kept running I don't know !!! so a good move to put a nice new distributor in it...
Have gone down the boy racer route and fitted a rev counter !!!!!!!!!!!!!!!!!
Did you know the best revs to change gear in a GMC is 2000 any lower or higher and the gears crunch so there you go.
