Not worth it don't even contemplate a 2 door conversion.... It will cost far too much money in engineering let alone materials and mods to make it happen...
Door mods, seatbelt point relocation , moving the whole pillar back... , etc etc etc
Would be much cheaper getting a DX imported....
Tubed front ends for "crisp clean look" it just doesn't happen... Looks much cleaner stock... There are a lot of 70's that get good lock with the right LCA choice, steering arms and other mods without gutting the wheel arches...
