how do you change air condition line on 82 vette already have hoses

TimAT

Carefully. Have the system evacuated, (unless the Freon has already leaked out), and then remove the lines for the evaporator/condenser, and accumulator. The trick is they may be frozen in place. Dissimilar metals corrosion. Use double wrenches on everything. It may take some heat to get them broken loose. I would suggest replacing the accumulator and orifice along with all of the O-rings.

are you staying with r12 or are you changing to 134?if going with 134 you need to use the green orings.I took my hood off to replace the front line.

Yes that front lower fitting on the condenser hard line is hard to get at without the hood off.
