I used a regular set of pirches, however, I used a grinder to grind the drivers side pirch to fit the casing, you will also need to grind the bottom, were the pirch was factory so the U bolts will fit around it. I dont know how experienced you are with welding, but when you weld the prich to the cast casing on the drivers side, be sure to get it either mig'ed by a big ass welder, or if your using a stick welder, use Ni-Rod. Now, as per $810 for those parts, HOLY $H!T!!!! they are maybe $200 at the most.... you may want to think about a trip to Harrys you pull it, out here, parts are so damn cheap. dont dare spend $810 on those parts!!
