Hi
Just wanted to let the forum know that I've tried to mount coilover suspension on my '89 405 MI16 from a PUG 206 and it is a direct in the front.
I'm using a FK Automotive Street(German made) on mine and it works fantastic.
On the backend I had to drill out a bit in one end of the damper to make it fit. But this way it is VERY cheap to get a descent coilover suspension to the 405.
Regards Johnny
