360 pros & cons vs 318

Lol, no im positive... I know it started out as 5x4" bolt pattern, but the rear end was out of a 72 charger, and cut down, from what i was told by the seller... On the passenger side of the car and driver side, the axle shafts have multiple bolt pattern. Ford/mopar and chevy 4 3/4" , right now the wheels are on the chevy pattern. I want to change it the mopar 4 1/2" pattern for some wheels i have that are universal in both 5x4" as well as 4 1/2" but the studs are to long, so i cant just tap them out and move them, i have to cut them out and buy new ones. I need the drums as well to change the pattern over. Im pretty sure i need new brake shoes depending on the width of the drum right? Not a gm housing by the way. Its an 8 3/4 with 489 case/sg. The axle shafts look like moser,strange axles etc. Just no brand in the center or numbers to identify them. Im not crazy either...
