You could try eBay. Actually the screws and the little peg-nuts do vary but would not be very difficult to make if you have engineering tools. I need to retrofit such a tensioner in order to replace the "patent" spring loaded tensioner on a Parkside saw. The plastic has bulged allowing the springs to come too close to the chain. IMHO plastic+spring= a timer (this WILL self destruct - guaranteed)
