Can someone please help me, I have a 17' Magna Bass Tracker boat 1988 model. I removed the wheel hubs and need to replace the wheel bearings and the seals. Its very hard to read the numbers on the wheel bearings and impossible to read the numbers on the seals. On the bearings it looks like a K1 68149 number on the inner bigger bearing. It is a tapered shaft on the trailer. PLEASE ADVISE. Thanks so much, Rick
