Well Tempered Simplex arm and wiring


Does anyone know who makes the 5 pin arm wiring connector on the Well Tempered Simplex table, etc? The pins are smaller than most 55 pin connectors I've seen. I bought a WT Simplex plinth (platter and arm were missing) and I am modifying it for use with a self-made Simplex clone arm.

Can WT Simplex owner tell me the exact length of the armtube (not counting the black rubber stoppers of each end)? Can you then tell me the distance from the front of the armtube to the center the mounting bracket for the cartridge?  Thanks in advance. 
Can any WT Simplex owners measure their arm for me? I'd like to know the exact length, minus the rubber stoppers on each end. I'd also like to know the distance from the tube front to the center mounting screw for the cartridge bracket... Lastly, the distance from the tube front to the pivot point. This is for the Simplex 9" arm.  All measurements as precise as possible please.

Thanks a bunch!
