Good afternoon!

I hope this is a simple request. I need to replace the vacuum advance and clean the trigger points on my 450 SLC.

I am familiar with some pretty solid pinch bolts which hold the distributor on my other cars, but all I see on the Merc is a fairly wimpy bolt with an allen head off to the side of the distributor body. Is this what's holding it on, or do I need to get all bendy and go deeper?

Thanks!
Dan Davis
