Hill had some valve springs and retainers he offered the board for free. I jumped on it, thinking they would be great for backups in case the other used set i've got have any problems. Well, these ones from Hill appear to be in great shape. Very cool when members hook it up for other members like this. Between this and getting the ball rolling for the subframe connector group buy i have to say it is people like Hill that make gvr4.org the best forum i've experienced and i'm grateful to be a member.
