Don't know why the original post disappeared into thin air. Here's take 2.
Anybody used the CMK P51 D cockpit set? Does it include sidewall details?
It's designed for Tamiya's kit, but I thought I'd try fitting it in
I misunderstood what you posted. I'm 99% sure it includes sidewall detail
and I have found that most Mustang kits are for the most part the same. It's
hard to screw up a Mustang. So you should be ok attempting to adapt it to
the Italeri kit. Just work slowly and test fit often.
