SCSI internal cables - 50 pin Centronics Female idc, 2 x internal devices etc

I am hunting for some scsi stuff for a two-bay storage case.

I am in need of:

2 x 50pin external centronics female with internal ribbon/idc's for at least two 50pin devices.

I have a few single device leads here but they are too short and would need stripping down to re-make them.

I will consider anything you have, unused connectors etc. But I do not need anymore cases! (ended up with too many)

Thanks

Anybody able to help?
