If I may jump on this bandwagon, I too need the cams that un-lock the rear seat. I have a pair of square posts sticking out that do nuthin when I release the seat back.... HELP! I just installed the seats last Sunday and noticed this.....
John that's the same parts I needed except I only needed 1 cam. Jimacuda just pm'd me with the total for them and unfortunately I had to pass on them because a huge deal I had going where I was selling a couple sets of heads for $750 fell through. If you want them go ahead and buy them from him. I'll hopefully find some more later.
