1953 Chevy AD rear end swap advice/help

[Marte_Mcfly]

Hey guys,
First of all, thank all of you who have the patience and dedication to give the tons of advice and post all of your progress. You all are a great inspiration and help along this journey. So here is the deal, I've been studying this site along with a few others for some time, figuring out what kind of build I want to do and with that what things I need to get to make it happen. As the title says, I'm trying to find the right rear end and I'm having trouble. Of all the rears (camaro, Nova, G-body, 4X4 S10, Explorer ect) I am wanting to go Explorer because of the gearing/posi/disc brake it comes with. Only problem with that is the bolt pattern doesn't match the 5X4.75 Chevy pattern i already bought for my mustang II IFS. ALL THAT TO ASK THIS... I was reading a post and someone eluded that an Explorer rear could be re-drilled for the Chevy bolt pattern. Is it true? How would I go about doing this or getting it done if so? Any help is much appreciated. Are there any other rear ends that come with disk brakes for my application? I know about the kits. Mid 90's Blazer rear ends do, but although people say they fit, I don't see how by my measurements.
