Help with extracting current ROM from Phone HTC Mogul

[RyanMogul6800]

Hey everyone, I hope you can help. I have a HTC Mogul, titan. I need to get my ROM off the phone and save it as a .nbh file because the person that designed the cooked rom is no longer supporting it. I did not save it and I cooked my own rom and have downloaded other roms but if it doesnt work out I would like to be able to go back to this one(as it works perfect on cricket). The rom I am trying to get out of my phone is To0's PPC6800 V.3 rom. If you have advice let me know. I am getting used to build os, and various tools just let me know what I have to do. Thanks
