RE: Reliable sources for rebuit WBX engines
Not knocking Boston Bob at all but if you are in the NW then NW Connecting
Rod has a very good reputation for their engines around here.  Only one
personal experience with them, a rebuild that went into my '85, ran great
out the door and was running fine when I totaled that Westy with 6,550 miles
on the engine.  One limitation, I've been told they will only sell to
approved installers so DIY mechanics may not be able to buy from them.
