Thanks Fred,
I have already bought a set of the head rests from Legendary and they aren't that great to be honest. Not quite the same contour along the bottom of the foams nor do they want to sit all the way down in the slides like they should. If I can't find a decent set of originals, I'll work on these and perhaps alter the post (or slides) to make them bottom out. If you look close you can see they are 1/2" proud of the seat and don't drop down properly. I did put aftermarket slides into the cores as the old ones were cracked and might have to look at the slides as well to ensure they aren't contributing to the problem?
