1985 380SL Ignition Timing
OK, I need to re-time my '85 380SL and need to know the size (mm) of the hex head bolt holding the distributor down and if I need a special tool to loosen this bolt. Any info is appreciated.
Thanks!
Thanks!

It changes all the time
Haven't retimed an M117 engine in years, since it is breakerless ignition. Only need to retime with major engine work like valve job. It should be a 13mm, or 10mm hex. If it's allen, it would be 5mm or 6mm. I'm quite confident it is 13mm and no special tools required. At least I've never needed any in 35 years.
