I'm surprised your Datsun has SU's. Those are British I think. The joke goes that Smith Union also makes refrigerators and that's why the Brit's drink warm beer. <img src="http://www.catsailor.com/forums/images/graemlins/wink.gif" alt="" />
They are Japanese SUs made by Hitachi I believe. Of course the guys over on the Datsun roadster forum think they are miles better than the British Sus. Presumably, when the Hitachis are set properly, they will stay set for quite a while. It has not been my experience though and they are newly rebuilt by one of the best companies in the business. When they are in tune, it runs sweet and never misses a beat.
