I ran 35s, on a 66 800, 283 chevy, T98a, with factory twin stick 20... front was Waggy 44, converted to 5 on 5.5, rear was Scout II 44, 4.88 gears, and spool rear, SOA with YJ rear leaves at all 4 corners, reverse shackle up front and stretched the wheelbase to 105". But I am a big fan of wide front and narrower rear axles, easier to keep the rear in line, and building with as little lift as possible.
I had 0 turning issues. The frame isn't that wide, and the correct offset and steering set up should give full turning.
I will have to dig up pictures, but mine was several inches lower than MotoDave's good looking scout. IIRC it was maybe 72-74" from ground to the top of the hardtop.
With what you are wanting to do, use the 58" WMS set up for the Toy front axle and go. Drive train combo you listed should be good.
