Where can I get a lwr case gasket set for the 587 white engine?
Had full bore rework cyl and new pistons,which they sent me a
top end gasket set....thanks guys
There isn't a lower end kit. Your only option is top end which you have and a complete kit. The ones I have used for 20 years without issue are the WSM complete kits. The number for yours is WSM 007-620 they are available on Amazon for $55 and free shipping.
