I'm selling a complete set of rocker arms for 1970-1976 Buick 455's. These were used on my Skylark for only a few hours before I invested in my first set of TA Roller Rockers. I bought the rocker arms as New GM and the shafts were bought as New Dana/Perfect Circle. Replacement rocker arm assemblies are selling for over $175.00, .... I'm asking $145.00 plus shipping. Larry
