Hi...I was hoping you guys could kindly help me. I just purchased a 1970 MB 280SE with the M130 engine. At some point, a previous owner removed the A/C hoses, compressor bracket and pulley. I'm trying to restore these pieces in prep for a Sanyo compressor and R134 upgrade. I found a compressor bracket on ebay, but I have no idea what the correct idler pulley looks like or where it is located on top of the engine. Is the pulley spring loaded? Is it affixed to the compressor bracket or the head? I would be most indebted if anyone with installed A/C could kindly post a few pictures of the pulley and the attachment, with belt routing. The configuration for the M130 on a 280SE is different than a 280SL, where the compressor is down low. Any help most appreciated. Many thanks! Joe
