...he had m23 armament and the twin 60 Cal with the 7 x rocket pod...
Both of the above systems were not used on the same aircraft types.
The M23 doorguns would have been on a UH-1D/H as in the Revell kit. Only door guns were used on US UH-1D/H long-bodied hueys. Called "slicks", since they were primarily troop transports. No UH-1D/H had the below, M6 system, or any other type of gunship armament configuration.
Cobra Company does an M23 Doorgun set in both 1/32 and 1/35.
The M6 system (quad M60Cs w/2 M158 2.75" rocket launchers) were only used on short-bodied UH-1B/C Gunships.
Cobra Company also does the M6 system in 1/35 to be used on a Sentinel/SAR UH-1B, or on Academy's excellent UH-1C kit. CC also does a UH-1B backdate set for the Academy kit.
Additionally, Cobra Company also does armored pilot seats in 1/32. These were in just about every Vietnam huey except the very early ones.

You could also use some of the Eduard 1/35/32 UH-1C PE on the interior and exterior for added details as well.
