      C6 upper ball joint taper? silver69camaro?

      I need to know the upper ball joint taper for a C5/ C6 spindle. Tried to measure the taper from the stock C6 UCA but I came up with 7.35 (or something) degrees. Figure this is do to the chamfer on the big end of the hole but not sure because a web search says 7deg or 1.5" per foot, 10deg or 2" per foot, or 7.5- 8.5 deg. Not sure who to trust besides the people here.

      Thanks for any help

      The most common taper is 1 1/2” per foot (1:8), which is 7.181 degrees which is rounded off to 7 degrees. The second most common is 2” per foot (1:6), 9.594 degrees which is rounded to 10 degrees. This is what I get for the 2010 Z06 upper and lower ball joints and the tie rod ends . Others are 1” per foot (1:12), 4.780 degrees and rarely 1 in 10, 5.739 degrees.
