Thanks! 1998 was when I started this dealership journey. I was a lawn tech fresh out of highschool. Pulled at least a few hundred of those LT series out of the crates brand new!Will you right it appears they weren't made until 1998 and LA140s weren't around until 2007 according to what I can find.

No way your LT155 is a 1989 model. Can you give the serial number please? I work for a dealership, and that model was not in production then. The short answer is no, the hoods are not compatible, but anything can be done with the right tools and ingenuity.
