I have always said the many countries have a far superior method of housing construction than that which is so widely practiced here in the USA

I'll return........

meanwhile, about the delay.
it's after 0115 and i've been under the kitchen sink all day. when not making parts runs to home improvement stores. old garbage disposer sounded tired, so tore it out. a brand new [Feb 1996] US made 3/4hp awaiting use. well, that brand uses a sink flange, backing nut and rubber boot to hang the unit itself. piece o' cake, right? of course not ! there is zero thread allowance between nut and flange, super hard to turn, and despite many tries, couldn't seat the thing without disturbing the plumber putty. no one local sold replacement nut, hopefully that would be machined not molded. the impedement forced me spring for new disposer with the other version of mount, the three seating screws.
