I just bought a 97 larson, half of the ladder is missing. I don't want to take the part off the boat as the guy just had it "fixed" and made solid. can I buy just the telescoping part? I have searched and haven't been able to locate just that part. Do you know if any telescoping ladder will fit on the frame? I assume it is original, there is a sticker on it that says Estran Coporation Two Rivers Wisconsin. Thanks...
