Hello all I am hoping someone can help me here, I need a sector shaft out of a 1985 Trans Am with a WS6 steering box. The ratio is 14.7 to 1 and the sector shaft gear is non variable. This means all three gears 0n the sector shaft are the same length when you look at it. Mine is grooved from years of an old dry deal cutting into it, so after my rebuild it leaks real bad through the sector shaft seal. If you can help me with a sector shaft in good condition please contact me Thanks in advance : )
