Hello, we bought a SL R129 280 built in 1994 last week. When we bought it, it was clear to us that we had to change the cylinder in the ignition lock immediately. And as long as it could still be turned I would like to do it. I have been driving a W 124 here for more than 10 years. The exchange takes only a few seconds with the right tool. Position one exactly to the point then with my processed bicycle spokes and swups is this outside. Well h I’ve been looking for the R129 in the net for a long time. There are way too many things.. somehow got completely confused.That would be so easy for the year of construction. Can someone please help me? Is the procedure like the W 124 it? Or do I have to do something else to set up and install the cylinder!? Is there a guide for this? I already have a new cylinder. Thank you for your help.
