Pull a part on the west side of Cleveland (Ohio) has a 1970 GS listed as just in on their web site. Just putting it out there as I'm not on the site here as often as I used to be. So good luck and have at it West and Eastsiders.
That poor thing is toast. Was hoping to find something useful but couldnt. But they did have a lancia there lol who needs parts from that gem.
