It's been a while since I've been here, been real busy lately. Anyways my Uncle and I removed the rear end from our Comet to clean it up and paint it and I got the tag off of it. I was wondering if anyone could tell me about it. I'm pretty sure it's an 8" rear but that's about it. The code is WDW-U 3DB 3.00 8 5210. Thanks for any help!
