Ah, if they are actually custom made, I get that. That is why I had suggested a local driveshaft shop who could have done the same thing here. Unless, they have found an aftermarket distributor for the rear axles.. in which case I would be curious to know what they are. Can you post a picture of them once they arrive? If there is a brand and/or model number on them.. I would like to find out what they are.
