Home Tiller

does anyone know any shops that might have parts still for the modle 5020 tiller. parts aren’t real specific. shops that do have old stock info. i don’t want any lame answers of any sorts. i am a certified tech for stihl and such and do my homework on things. this is a very rare item that you don’t see much of especially on ebay. ardisam themselves do have certain parts still but very few. this tiller is very very similar in parts to the troybilt pony but part crossover is very impossible. i have done trial and error with a few internal gears and such but the main worm gear shaft is a bit too much money to waise on this. i am in indiana if anyone happens to have one in very decent shape close to the plymouth indiana area. let me know….thanks
