Also there is no brakes on this rear end, so should I just go for 11 inch brakes or what? If I do, where is a good place to get a set of brakes for this rear end?
10 inch LBP drums are the most common and can be found on most all B, E, C, F, M, J and various trucks if they are equipped with an 8.25 or 8.75. I believe some 7.25s with the LBP can be swapped as well. You should be able to source them locally in your Pic-A-Part or from someone selling them here on FABO. 11 in rear brakes can be found on B/C/E/some trucks as a HD option.
A 2nd rear brake option is to convert to rear disc brakes. Dr Diff sells a kit. A FABO member (dodgedifferent2) makes the brackets for the base Mustang 94-2004 rear discs. You source the rest of the brake components locally
If you currently have the SBP/9 or 10 inch front brakes, You may want to swap to LBP front discs in order to carry one spare
