Bill,
Thanks again.... I looked at the rad cap I have now...looks pretty new...and it has a 9 stamped on the top....I'm guessing that would be 9 lb. ? I'll take it in to Riebies today and try to get a 4 lb. The shop I mentioned is 30 miles away...I'm kinda goosey about driving it that far if it is overheating...and I dunno if it really is. Gonna call them this AM and see what they say they can do...and if they have experience with these old ladies...
