Thanks for you’re answers guys , that’s may the 62-65 TTI headers may a bid longer as the 66 up TTI ‚s ? In my 68 charger are no original k- frame . Is a independent front suspension from freak control with a 426 Hemi . That means I think I can use also the „new“ 62-65 TTI s , there available also in 2 1/4“ pipe size and not as the 66 up only in 2 1/8“ pope size .... right ?The 66 up cars the engine sits back further. At one time TTI only sold sets for the newer K frame.From what I understand now they make them for the earlier K using Schumacher engine mounts.
