Hi again ps2fixer, The two attached pictures are interesting. Have not taken my unit apart so I don't have a reaction yet. My pictures are somewhat confusing in that they are of both the blue US90 and the red ATC110. The 90 is together, while covers and such have been removed and not replaced yet on the 110. Neither gas tank is/will be hooked up, using funnel and hoses to get running only (reason for your observation I suppose). Any pictures of the splines on the axles? Have a junked ATC90 of a later year (like 75/78) and the front wheel axle is mountable as is the axle from the 110. One of the pictures shows the 110 wheel and axle on the US90. In my last two attached pictures do the tires shown in the stack of 3 (removed from the 110) appear to be original type? Ok, now we're talking details! Went to the site showing the yellow US90 advertisement. On the big top picture it is shown without the rubber axle nut covers on the rear, why not? There is what looks like a sheet metal belly pan with a large (maybe inch and a half) hole in it, what is it. The foot pegs seem to have a latch like mine without the additional vertical reinforcement as sold currently as a replacement, which is correct? Also the foot pegs don't have the fancy brush bars as shown on the blue Honda factory restore seen elsewhere, which is correct? The seat is pleated, early or late? The clutch adjusting screw/nut does not have the black rubber cover, early or late? Lower smaller pictures seem to show a "gold" color, was their one? and what year? Now see what appears to be a belly pan with three large holes on a head light less unit, what years was it used? Also some of the lower pictured units have headlights and some do not: Dune Buggy (no light), Rock hound(lights with fork ears), Snowmobile (lights with fork ears), beachcomber (no lights), and Water bug (lights with fork ears). Bottom pictures show wheel being slipped on to unit with an "air pump" but no tool box evident, is it located somewhere else? Last observation, the use of the description "Honda ATC 90" in the add would indicate it is not an early advertisement page at all! All this just adds to the confusion! Come on guys lets get some clear details. You guys with the basket cases can help some, but the people with the one owner stuff, or anyone with truly early advertisements or brochures should be able to shed way more light on the subject. Where are you hiding, lets start getting a list of serial Numbers or at least a "range" of the numbers and other obvious details like foot pegs, grab rails, rubber goods, etc?
