I have the Dvorak stands on my SS/ba dart clone. I went with them because being an a body there isn't a lot of room to work in the engine bay. Also liked the idea of being able to pull the shafts without disturbing the head bolts. Cost was close to a grand and I think I got them in 07 or 08. I've never had any issues related to them, but remember that they are offset some from normal. Dan will help you, when you can get in touch with him. My car is a cruiser and I have put about 10000 miles on it since 2010
