Wanker Posted November 12, 2008 Posted November 12, 2008 What is the spline count on the output of an AW4? Don't have one near me at the moment, or I would check it. Is it 23?
johnnyc Posted November 12, 2008 Posted November 12, 2008 Depends on the year. I believe that it was 21 spline up until 1989. Then 1990 and up are 23 spline.
reson46 Posted November 12, 2008 Posted November 12, 2008 Depends on the year. I believe that it was 21 spline up until 1989. Then 1990 and up are 23 spline. Close. '87 to '90 is 21 spline. '91+ is 23 spline. Willy
Wanker Posted November 12, 2008 Author Posted November 12, 2008 That's great! I appreciate the help guys. :cheers:
carnuck Posted November 14, 2008 Posted November 14, 2008 The Aw4 changed over to 23 spline with the arrival of the 4.0L HO in 08/90. I took the AW4 out of an 07/90 only to find 21 spline (after paying $600 for the parts rig)
