I just completed a conversion on my 70 Challenger. It was more expensive than 3000.00 partially due the the expensive pistol grip. After thinking it over i ordered a complete conversion from Passon's. To me that is the way to go, buy the kit. I think it would have been more expensive locating and paying shipping on all those parts separatly. The kits have eveything you need including the proper bolts. I think done correctly it would add what the cost is to the value of the car.
