Hi, this seems to be the wrong part for my trimmer, but I am not finding the correct equivalent Mine uses 0.080" line, and has a red retainer knob (LH I think). This one is 0.095" and RH (black knob). What are the correct part numbers for the housing assembly, and the spool (if it doesn't come with the housing assembly)? Thank you

Lent my trimmer to a family member ..... while attempting to replace trimmer line, he did not realize that the spool retainer was reverse - threaded and tried to turn the spool retainer counter clockwise until the red plastic housing was damaged. I had to grind away red plastic housing with grinder to expose the spool retainer bolt. Onc e the bolt was exposed, I removed it with socket and replaced it with the new spool retainer assembly. REMEMBER.... SOMETIMES BOLTS ARE REVERSE-THREADED.
