I got a new compressor for my bimmer at advance auto. The # all the parts places are pulling up is 10PA17C but the remains don't say nippondenso or the sieko on the back. The problem is you have to change the cap on the top of the compressor that holds the high and low pressure lines on and the remains spot where your suppose to transfer the cap is about a 1/2 inch longer so two of the allen bolts don't even get close to bolting it down, correctly. Has anyone else had this problem, is there a crossover reference # or do I have to break down and get one from the dealer for over twice as much. Mine is the nippondenso 4 grove style.
