I have a 1979 K5 Blazer and I am installing a 3" body lift. I have read many different theories on the steering correction. I am trying to loosen the entire column and I got the bolts inside the cab no problem but the two clamp nuts on the firwall are covered with undercoating. Does anyone know what size these two nuts are so I can hammer a socket on them. I left aircraft paint stipper on them all night and I have yet to go to the shop to see if it ate through the undercoating. I have also heard of people heating the plastic pins in the slip joint to extend the shaft, but I needed to adjust my column anyways. Any information on the problem or a cure would be greatly appreciated.
