Bruder conversion dozer/excavator tracks

[RcBruder]

so i have done a few conversions with the little bruder dozers and have had alot of fun with them until the tracks started wearing out and then they start to slip to the point where i can start taking links out and it works again. Thats alot. i am just wondering if anyone has seen or used any other types of tracks for these or know a place or someone that makes or machines new ones? Preferably metal ones. Thanks everyone!
