Both are easy to make. George P. may have some on hand. Go to a Tandy store and buy some 3-5 oz leather straps. Trace the old guides or cut to the size need, wet, mold around 1/8 or 1/4” wood, and let dry. Punch some holes for brass screws. Thee was a poster on EBay, from the UK, who sold cases traps. He may have some.

Good luck.
