hi CuzzFuzz, assuming the later model 235 will accept the same flywheel as an early 235 i suggest you call Turners auto wrecking in Fresno, they likely have the standard 9 bolt clutch and flywheel assembly out of any 3/4 or 1 ton truck from about 1940-53 years. the trucks shipped with a 10-3/4 inch disc, that's what the parts books all reference and that's what my tape measure shows on all the ones i have pulled to date. it will be the same flywheel and clutch for all engines.
I measure the flywheel and pressure plate in my 1 tons (50-53 years) and the assembly seems to be oversized just enough that if you did find the full 11 inch disc it should just fit wall to wall perfect. but i have never tried to actually fit the slightly larger 11 inch disc yet.

JimCarter truck parts sells the 10-3/4 inch clutch MEE257 for about $78, the filling station also sells the same one but for a bit more.
image of the typical 9 bolt clutch attached, if you were closer to me i would just give you a whole assembly flywheel and clutch, i have a dozen of these on my farm. best of luck. -s
