On my 89 Fourtrax 300, the plastics are broken and dry rotted. I have noticed that the rear fender is no longer available. So i have an idea to replace the 89 rear fender (80100-HC4-507ZA) with the 1997 TRX300 A rear fenders (80100-HM4-A10ZA). from pictures and the schematic, it looks to me that they are fairly close. My question is will it line up with the seat, and will it bolt to the frame in the right spot. the rack i can make work regardless. Thanks for any help and guidance in this.
