I’m working on the air conditioning upgrade in my ‘68 280 SL as described on the forum. I’m using a sedan compressor bracket with idler pulley but this pulley does not align with the center groove on the crankshaft pulley. Alternator and power steering align fine. A picture on the site shows a comparison of the SL and sedan pulleys and it looks like I need to install the latter but I’m not sure about the correct part or part number. I wonder if anyone can advise me on a source and/or part number. Many thanks.
