The #86 camshaft was also used on many sedans of the era, in case you want to go on a quest for a good used one. The cam supports are very pricey these days also. Now do you really want to run used rocker arms on the expensive new camshaft?? Costs tend to spiral out of control. Now you have to consider those used ball studs and contact pads ? $$$ SLS is near to you. The MB dealer is an option if you get with a good discount might be a good option.
