I have a 1989, (I think), Trail Boss 250 that needs a new ujoint. I’ve completely disassembled the body, and still haven’t found a vin tag, or numbers in the frame. But the sticker on the motor, and transmission sticker make me think it’s a 1989. Plus it looks like an 89’ from the pictures of others I’ve been seeing. My question is if there are differences in the ujoints between years on the Trail Boss 250’s. I can find parts for a 1990, but not an 89’. I’ve attached some pictures. Thanks for your help.
