astrro powermig 130 wire feed tensioner

[poppawoody]

I have owned this astro mig 130 which I purchased from snap-on for over 30 years and have only used it a handful of times. the wire feed tensioner (plastic) brove where the tension screw houds down the arm. I found a listing for a new unit Tensioner # 334-635-000 but it says discontinued or out of stock. Any ideas on where I can find a new / used or replacement wire feed tensioner assy or just the arm that holds the roller.

got a pic someone might have an idea to rather than replace

there are some on here replaced the compleat drive unit with bits of ebay for quite cheap but it can be a bit of a fiddle
