excellent, thanks

 

It's not a bad write up. Andy used to be a regular here, might still be. When he came up with his first version he advertised and marketed it here. Looks like a good product, and he's a heck of a nice guy.

At the same time I've never been able to justify the cost. Instead I usually just replace the pins and bushings in the lower hinges, and use a floor jack under the opened door to bend the door back up and return the hinges to the original shape. I've done about 5 cars that way and it's cured the problem every time. Total cost is about $10/per door.
