Homebrew Coilover setups

Hey guys , I found some torsion bar crossmember issues with my 69 dart last night as I was preparing to install larger torsion bars. I think the easiest way around this is to install coil overs up front. I know that they make ones that replace the factory shocks. With these I also know you need to reinforce the upper shock mounting area, I would like to see some ideas on how you are doing this. What are you guys doing to retain the lower control arm ? I am not looking to buy a whole new K frame setup. I already have upgraded front disc brakes and tubular upper a arms. Thanks for your help !
