pivot pin 2 1/2" metal, and quick tilt plastic hinge it inserts into

Hello. Start by looking at the 26-398 Pivot Bar, this looks similar, but please review to confirm. This bar works with loads of different pivot shoes. The Series 140 system is a possibility, but you'll have to actually inspect the shoe to see if it matches up. Let us know if you have questions.
