you are right stuart, and i always have my best luck sticking with stock matching stuff too- really no matter what. with all my work this weekend on it i'm going pretty wild today wanting to chop driveshafts and drill flywheels. thaks chevman32 i always over look the simple answer. i might call the machine shop and see what they would charge. i might even take the larger flywheel in and get the dowel holes too. hr
