eagspoo,
Sorry to be late on a response.
If I am understanding you correctly you need the actual fence rail that the Shopsmith OEM Fence uses. That would be part number 516687 called the
Bandsaw Table Notched Fence Bar and is $27.95 plus you would need the 3 Hex Head Bolts and 3 Flat Washers. If I recall correctly the Bandsaw Extension Table Accessory (P/N 555488) Extension Bar (P/N 501378) is the same part without the notch for the Miter to pass over.
The picture below shows the Shopsmith Bandsaw Fence, Fence Bar and hardware.

Although not relevant here, the Fence above the second version with locks on both ends. The Fence Bar and hardware is the same for the earlier version single lock Fence.
