Interesting find Dreamer.
I see no reason why it would not physically fit as they made few changes to the body for the M.
That said you'd have to figure on lots of differences such as the narrower wheel track and potentially anti roll bar interfering with the dual one side exhaust. The gearing may be good or bad depending on what you want to achieve and what you currently have.
Frankly I'd steer clear of something that's so rusty, needs springs, dampers, new discs, pads, different track wheels, etc and with then need new front rotors to balance the braking.
