Was this vehicle in a major collision or has someone put different doors on it??
How are the hinge/striker posts??
Is the frame straight??
You may need a replacement top hinge on your "drivers door" as: It's used the most. I replaced mine (74 Impala) which is a similar design. Check the 'pivot pin' on it.
Having to re-align all 4 doors is rare unless the vehicle has been 'wrecked/abused' etc. Perhaps Micky Mouse was there before you got it.
Either way, you don't need a "Rod Shop" for this. Simply; go to Body Shops in your area & get (free) estimates, is all.
Happy trails.
