For something you can convert to the M60, the M26 Pershing by Heng Long is your best bet. Notice I said earlier that the M60 can trace its lineage all the way back to the M26? Well it's true. The hull shape and layout of the running gear is almost identical to the M60. The turret will have to be modified to change its overall shape, and that's the biggest thing. Otherwise...

Remove two return rollers per side
Flatten the glacis/remove coaxial MG
Change rear engine compartment/hull

Other minor details could be had by scratchbuilding or the proverbial "spares box".
