P-51B or C radio compartment????

Getting ready to do the Revell "51B" in 1/32nd and looking for either photo's or line drawings of the radio compartment. Was able to get good cockpit shots of a "C" model at the Lunken airshow but the A/C has a second cockpit instead of the radio compartment. Any photo's, drawings or info and or advise will really be appreciated. Thanks, Swede P.S. Anyone done the Rutman 1/32nd "51B"? Thinking abour it if its worth the $95 bucks.
