Do you have an original AM General slantback hardware or are you going to buy a slantback conversion kit from some company? Or maybe you plan on fabricating your own? Right now slantback hummers are going for about 80k and up no matter the year. So original slantback hardware would be pretty expensive I would think, if you could even find it. Conversion kits run about 3k to 5k. Also if you plan on someone else doing it for you that's going to be a lot of money too.How much would it cost to change an h1 hummer into an h1 slantback? ?$3k
