If 2266 is a good number for what the op needs they are available at Oreilly's for $3.99 and that would save shipping if he has one close. Here I just have to call the store and they will order them in for me.
I ordered these knowing they would probably be wrong and I can tell you with certainly that they do not work for 66 dart with v8. I am going to order from Schumacher.
