Default 2.16.9.x Manually install OS/Radio Rom w/o Ext Rom?

I have a Cingular 8125. Is it possible to just use aWizard to manually install the OS rom and the Radio Rom? That way I won't have the Ext. Rom from the new imate 2.16.9.x rom right?

If so, can someone who has already run the RUU, send me the OS/Radio rom ? or tell me how I can extract those from the RUU exe file?
