old receipt showed 54" ctr to ctr (u-joint)...3.5" x .083"....but this one looks like he went up to a 4" with it.


Otherwise......if anybody's listening anymore...new d-shaft made it better but it still shakes like heck at anything over about 80mph. So...buying wheels/tires for it, been planning on a new torque convertor but will add a new sfi rated flexplate to match. Hopefully I'll get it calmed down good enough to head to an 1/8mi track this weekend.
