Wanker Posted November 12, 2008 Share 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? Link to comment Share on other sites More sharing options...
johnnyc Posted November 12, 2008 Share 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. Link to comment Share on other sites More sharing options...
reson46 Posted November 12, 2008 Share 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 Link to comment Share on other sites More sharing options...

carnuck Posted November 14, 2008 Share 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) Link to comment Share on other sites More sharing options...
