WP pulley...480 is correct ( superceeds this # 3906656 7.25"
Crank pulley....978 is correct, has 3 grooves. (make sure it is the correct diameter)BUT if you are not going to install the idler pulley and bracket, use the 2 groove belt pulley. NOW, you also have to get the correct PS bracket and pulley, also the alternator bracket and pulley, along with the correct water pump. It will take you awhile, some trial and error needed. Unless you have a non-numbers matching car, then you can substitute some other pulley numbers. *** NOTE...get the correct measurements for each pulley, most are listed in the parts book. PM if you need more help
