Putting together a clearvue cyclone and trying to put the straight transition on the blower housing. Anyone done this and how did it go? You're supposed to insert a couple block spacers which each have two holes and tighten the housing to hold them in place. If I tighten this at all it can cause the blower housing plexiglass (name?) to bow. Am I missing something. I'll call clearview tomorrow but thought I'd get some advice from u who have done this.
