I'd try http://www.amp.com to get a part no, if it exists, and then search around for someone who'll sell it. I'd also check Kingston- the folks who make slide rail carriers may have this. I'd doubt that this is a great idea because the whole point of SCA is it combines signal power and mounting in one deal- to go form SCA, you'll have to come out with both the MOLEX +5/+12 connector, the 68 pin cable connector, and it won't necessarily have the right mounting and any length of 68 pin longer than 50mm is gonna add signal noise.
