I've seen them for 600.00, but never paid more than 150.00. the truth lies somewhere in the middle....
Good answer Rhett. Asking prices have gotten out of hand, $300 range is typical, but I wouldn't pay that much either. It really depends on who is selling it... might be under $150 if it's from a junkyard, or $350 if it's advertised on a Buick board.
I've still got a set for $500 Canadian, just a warning, shipping would probably be stupid expensive. Carb needs an overhaul, but it's correct for a 66 Wildcat with a 425. .
What part of Canada are you in? I get to Sault Ste.Marie periodically and am interested. Also get to International Falls.
