Charles H Posted September 24, 2008 Share Posted September 24, 2008 Post 1974 2500's had HS6's with a longer tract inlet manifold ;) Link to comment Share on other sites More sharing options...
piman Posted September 24, 2008 Share Posted September 24, 2008 Hello Ngtraderman,HS6 have a four bolt fixing, while HS2 have a two bolt fixing. The size of S.U.'s are given by the number, 1" + (number x 1\8"), e.g H.S.4 is a 1" + (4 x 1\8") which gives an 1" + 1\2", i.e. 1 1\2".Alec Link to comment Share on other sites More sharing options...
