On a stupid impulse I bought a set of M.S. seat on fleabay(that was before wire was around)
They were too wide. I have '96 Gen 2 seats in right now. They are wider at the top than the gen 1s but not a real problem.
Gen 2s are flat on the bottom of the seat so fit right on the gen 1 frame after you unbolt the gen 2 mount. You only need to drill 2 holes on the gen 1 sliders, the gen 2 seats are 1/2" shorter or <img src="/forums/images/graemlins/confused.gif" alt="" />longer.
The M.S. seats have a "staggered" mount on the different level floor, like the gen 2, only you would have to grind the mount off instead of unbolt it like you do with gen 2 seats. Then I'm not sure if you have enough lip to drill holes in or if it gives you the flat bottom you need
In frustration I traded them to a yard for some fair gen 1 seats just to get them out of my small apt.
Good luck...
