Id suggest buying new items with things like that, prevents things from $$% out in the future. Got mine for about $20 new. But I dont have one for sale sorry.
yea, just go new- I got a tridon one a while ago, was only about $14. have used them in many cars without issues. repco and supercheap should have them.
For the cost of a new one its really not worth putting a secondhand one in, especially since you dont know if its ok or not.
