I would check with the local supply company as they probably stock a dual meter main that is acceptable to the local power company.

Ok, thanks. my first residential job where I had to split the service. Just thought about it and realized I had one wire in, 2 meters to feed

Go parallel in, separate out? Right?

Not necessarily. A typical "two gang" meter socket used in this application may have single line side lugs that accept up to (1) 250 or 300 KCMIL conductors. If no main breakers incuded in the enclosure, and 100/125 amp meter jaws, it may only accept up to (1) 2/0 load side conductors.

BTW if you have more then one service disconnecting means, you don't necessarily have to have 200 amps of supply side conductor ampacity. Many do that anyway and is not a violation, but if total load calculation of both units were only 135 amps your common supply to both meters could only be a 135 amp conductor (1/0 copper or 2/0 aluminum) even though you do need 100 amp conductor to/from each individual service disconnecting means.
