header delima...

I agree with most of the above info. My '69 Dart when purchased, had tti headers and had the same tube hitting the steering linkage, almost had a slot cut through it.
I cured that problem with a full aftermarket front suspension, but, ran into it again with the oil pan hitting the rack and pinion. This is when I found out how much you can move the engine up and down with the 3 engine block/ bracket bolts. Loosen and lift engine, engine sits high. Loosen and let the engine hang low, engine sits lower. You would be surprised.
A lot of little things can add up to be one big thing.
