If you do decide to replace the original style upper and lower front seals, do consider installing a better modern From the Frame Up style GA 125 Oil Seal, or a MOSS 120-750 seal.<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>Jon<br data-mce-bogus="1"></div><div><br data-mce-bogus="1"></div><div>SLC, UT TC,TD,TF<br data-mce-bogus="1"></div></body></html>
