Charlie, are those T&Ds Or Jesel Rockers? We Have the T&Ds ( about four years old ) and I'm wondering how you guys check your spring pressures on the motor. Can it be done on the motor? My friends have tools like the Buxton, but I don't think they have one for the Hemi. Do you modify them to fit or have another trick? Sorry to hijack, I just thought this would be the best place to try.
