Are Gen IV and Gen V Belly Pans interchangeable

[v10CodeMonkey]

Looking to buy a new belly pan for a Gen IV and am seeing the Gen V pans for considerably cheaper. Anyone know if these are interchangeable? I know DSE created a nice carbon fiber pan that fits Gen III, IV and V so assuming the bolt patterns are the same. Anything else that might be different on them causing them not to be interchangeable?

The Gen5 pan is thinner. Doug Shelby’s design moves the diff vent closer to the diff. 05290078AI is advertised as superceding 2003+ to cover zgen3/4/5.

T 05290078AI is advertised as super red 2003+ to cover zgen3/4/5.
Interesting, because I don't think it has the cutout for the Gen3 ring-of-fire exhaust.

Correct, Gen4/5 don't have the opening. The original question was Gen4/5, I just tossed in the Gen3 for good measure. The Gen3 can accept the 4/5 pan, if the Gen3 is still using the crossover then it's not difficult to cut the opening.
