CAREFUL, here. In earlier years, BEFORE IH started using Dana 60's in the
rear of 3/4 tons, they had an axle that LOOKED like an RA15, but was
smaller. Think sort of halfway in size between an RA15 and a Ford 9". These
ALSO had 6 on 7.25 hubs, drums, and wheels. Which is not to say that you
did NOT get an RA15 in a heavy GVW optioned 3/4 ton !!

As for the thing about 16" wheels over 14" drums--MAYBE they go if you are
talking about 16" SPLIT RIMS, but NFW with 16" drop centers !!!!
