I've been attempting to upgrade the front brakes on my 1988 190E 2.6 with those from a 500SL.
There have been various problems along the way most now resolved. However, due to the fact that I've had to use spacers to create clearance between the wheel inner (17X7.5 AMG replicas) and the caliper I now find that the wheel bolts need to be 13mm or more longer at total length from under the bolt head to the end of the thread of 52mm (or more).
I have spoken to a couple of Mercedes dealerships and they are not interested in helping me in any way, in fact I was very dissapointed with their attitude.
I was wondering if there is another model in the Merc range that has longer suitable bolts for alloy wheels, maybe the ML for instance.

Does anyone out there have any ideas?

Any help would be much appreciated.

Many Thanks.
