I've been searching back posts with no luck on the preferred .91FX replacement backplate and separate bracket (stay) and needle valve assembly. Are the ones for the .65LA the ones to use?

Further digging found these:
OSMG7152 26582931 NEEDLE STAY 91FX 65LA $2.99
OSMG6997 26582900 VALVE ASSY 40-65LA $19.99
29057000 COVER PLATE 91SX-H $$12.99
