The Mamiya Sekor 1000 DTL was a really nice camera in its day. If I'm not mistaken you had a choice of spot or average metering patterns and that was a really sexy selling point back in the day. Nice camera though. I always wanted one. M42 lens mount too! What else could you need?
I digress. I found a listing for something that might fit the bill for you here: http://www.adorama.com/US%20%20%20%20136280.html or here: (link). If that doesn't work for you why not consider getting one of those cheap "L" flash brackets like this: (link). Sure it makes the camera a little tiny bit bigger to handle; but on the plus side, it adds a bit more stability to the whole rig and get the flash a bit further away from the lens axis. Instant red-eye reduction without the associated pre-flash and electronics.
