67 Barracuda project... narrowing 8 3/4 rearend

I had hoped to save some on the axle so I could go forward with suspension and transmission at the same time, Moser was my first choice but is very pricey. If I did go with moser should I consider the Dana 60 or 12 bolt? I was looking at: Ford 9" inch nascar rear end housings , chun for sale in SPARTA, TN, Price: $135 but of course I'm going to have to do a lot of research and build it myself (part of the fun!). Though I do know I will need an experienced person to set up the differential.
