I took the advice of Janson and went the fabrication route. I made full size drawings of the ram guide from multiple perspectives and decided on using 1/2 inch plate for the two curved side pieces, 1/2 inch x 1-3/4" x 1-3/4" angle iron for the front "grooved" piece, 1/4" x 1-1/4" x1-1/4" brass angle iron for the front liner and 1 inch thick plate for the two side mounting pieces. The curved side pieces were cut out using flat card stock patterns that I made from the original guide. They were bent cold in a press at L&M Steel in Brainerd, Minnesota where I buy steel. The brass insert was held in place by threaded brass screws in the center of the angle iron. L&M Steel also drilled and milled the oval shaped mounting holed (three on each side). I fabricated a frame to hold the 5 pieces in proper alignment for welding. The pieces were welded, cleaned up and painted. The new ram fit in place nicely and a new die key was fitted and installed.
