1973 duster wheel bolt pattern

Both were factory /6 cars both by k member and vin tag. I removed the /6 out of this one, and my last one someone had put in a v8 on the /6 k member by bolting in one side and using a chain from the block to the inner fender well. Everytime you accelerated it would lift the engine into the hood and dent it. I pulled the k member out and put in a small block v8 k member in out of a wrecked v8 dart sport I had, as well as the 8.75 from it. The last guy that had owned it did the half *** swap in of the v8. He told me he had pulled the /6 out and did the swap. If you want to call it that.
