65 Barracuda Brakes... Help

Hi, I'm new to the forum, recently picked up a 65 barracuda. This is my first mopar, looking forward to building it...

Anyway about the brakes...just got the car running this week, but brakes need to be replaced immediately.

Looking for drum to disc conversion kits that people recommend... AlsoI have the small bolt pattern and read that most people swap out the 5x4 for the 5x4.5 when they convert to disc brakes. However I'm on a tight budget and am thinking about only doing the front brakes as disc, and just rebuilding the drums in the back... is there anyway to convert the rear drums to 5x4.5?
