I used wikipedia for the weight. Not sure how close it is. I also had a blown power valve seal that I found the week after doing this when I took the carb apart to find out what was wrong with it. It's much much more responsive now.

best thing for weight are those freight tolls with weighing stations. I never went there, but I hear give them a couple of dollars and they weigh you. if you arrive with that car you might get a freebie :-)
