Hey guy's.. Thanks for the manual link.. I bought this off ebay for $53 + Shipping.. it has a few scuffs on the lid.. but who cares.. it went in easy.. Pulled the old flat square one up and had to twist the flange ring to the left and lined the bolts to the holes.. It (the flange) looked just like the one you would see at a house toilet ...
HAPPY DAYS ARE HERE NOW... LOL
Never do anything you wouldn't want to explain to the Paramedics...
