A 216 balancer should solve your crossmember interference. It has a 5'8" pulley
A '59 235 has a low water pump which will not be centered in the radiator. It has a large 1/2" pulley and too long of a shaft. Not ideal
You can install an adapter plate to the front of the block to relocate a 216 water pump with a 5'8" pulley in the center of the radiator.
A 5/8" pulley can be installed on your generator or alternator.
