Where to find seats that fit 79 450SL
 

I recently purchased a 1979 450SL and, unfortunately, cannot get comfortable in the existing seats. I am apparently just too tall - no headroom at all with the hardtop. I am looking for replacement seats that will fit this automobile that would possibly address this issue, having a lower profile. If anyone knows companies that specialize in seats that may fit a 1979 450SL, I would greatly appreciate having the name or link.
