1974 Duster slant car---- big bolt pattern wheels, discs up front??

I ask because I found a 74 Duster project, and it is missing rear wheels. Itwas a fater son/projectthat never got started. Not sure if dad knows a drum from a disc! Once past the Turkey Day crazies, we will make the 6 hour trip there one way if not sold. I have had 6-7 Dusters/Dart Sports over the years and miss my last one. First rasonably priced complete project Duster project I have seen an quite a while, and that is not 2 state away. Beaks don't bother me! It even has a title!
6 hours is just down the road a ways in Texas.
