Man, they definately wont fit, you are going to have to sell them to me, if they are palomino and leather with buttons that would be great.
just kidding man, they front seats on the SEC frame rails should bolt right in. What you could do is mount the sec seats on your coupe frame rails so you dont have to install the buttons and such. I havent looked into the rear seat, but I would just say take it out and check. I bet its too wide, but let me know. I am just looking for an interior to do it before I start it. I know the front seats will fit though. You could make the two rear window switches do the back rest because you shoudlnt roll those down anyway. Let me know.
No Benzes in the stable at the moment, but itching for one again.
