i found a cool set that would be great to replace my failing mbtex horsehair ones from my 84 w123, this year i got into the engine, drivetrain and front end, now i just have to replace the dash, rewire and new interior and im super happy. so i found these w124 seats that look like they would fit, the rear im not so sure of but i want to try it. any thoughts? i have not found any info on this out there anywhere..
