I agree Jim,over the last couple of days,several twin carb manifolds have sold for as little as $30,one in really good condition didn't even get a bid at $60 so I'm not sure why people are spending that kind of money on a full set up.As far as I know,the carbs on the early grey twin manifolds were not matched or anything special unlike the X2 carbies (specified as being matched,and specifically stamped?).There must be millions of stromies around and I've noticed that just about all the linkages seem to be set up differently.Getting off the topic a bit here though,sorry....
