To my knowledge GM and Ford have front steering for a long time. The pinto for example since 1971, that I know of. They don't have bump steer or ackerman issues.

Why would he waste time fixing bump steer??????

Really?? you're asking that question... Obviously you've never driven a car with bump steer. It's scary and with any amount of horsepower, you can be sure you'll see the wall......

If he hasn't fixed it he should just to save his A$$ from a lawsuit.....
