This category is under used IMO. I have an original MustangII front suspension under my '35. It sits a bit high so I went with a QA1 kit for "mustang 2" to set it where I want it. I guess it works well for after market MustII cross members/tubular A arms but with an all stock it's a night mare to install. Also, once in you cannot run the base down to thread end as the stock spring base is in the way as it also is for the tension adjuster. ...not sure if I should weaken the bottom A grinding away or?? I'm sure people here have done this so help!!!
