Ok chums, I need to pick the engineering brains in the SL(K) diaspora. I'm going to ( let my mechanic ) re-bush the suspension on my 85 500 SL. I've been meaning to for a year or two now, but the combination of pin-sharp handling in the SLK, and the MOT-tester pointing out a deteriorating front sub-frame mounting bush to me have forced me to act.
For the last month I have chased down in the various corners of interwebland the front sub-frame mounting kit Meyle), front ARB repair kit ( Febi), front wishbone lower bush kit and camber bolts ( Meyle), rear frame bump-stops ( Mercedes-ouch) and rear shock bushes and fixings (Mercedes, not so much of an ouch). None of these apart from the s/f mounts have to be done, but why not.
I also sourced, via HistoMondial ( most helpful and efficient) in Germany, all the wishbone bushes front and rear in lovely red polyurethane and the front top and rear ARB bushes, including all the little piddly ones for the front
I ordered these come with steel inserts ( can be ordered without, but what the heck), and they don't come with any bolts. What I have done is swap the relevant PU bushes into the OEM repair kits I bought, easy-peasy. As the camber bolts alone were a massive £156 at MB for the four needed , the Meyle kit I bought ( with probably the same bolts and rubber bushes as a bonus) was only £50, and an absloute bargain in comparison. The OEM upper front wishbone bushes and rear trailing arm kits are a bit less of a bargain if all I want them for is the bolts.
I have sized the bushes with my fancy-schmancy calipers, and worked out that I need four M12 x80mm for the upper wishbone, and four M16 x90mm for the rear trailing arm.
The question is, can I just pop down to my local bolt supplier and ask for said quantity of his finest high-tensile zinc-plated offerings, or should I be looking to do some more repair kit cannibalising? I've examined the Meyle and Febi bolts I have already, and they don't look anything out of the ordinary , well except for that groovy camber bolt. They look like pretty standard high tensile bolts to me, but I'm no engineer at the end of the day.
