I've tried searching and everything that comes up varies.. some say the 5210 is a dgv and others say it's a dfv or something like that. I got it for free from a buddy who did a v8 swap on a mid 70s vega, I've got the carb apart and it even says webber on the inside. Problem is I don't know what adapter to buy to fit it to the e1 because of not finding out 100% if it's a dgv or what. Any info would be very helpful, thanks!
