I have a 302/c4 in a 64 alpine (still has stock alpine rear end) has anyone made a "driveshaft" that FITS the c4 and the original rear end ?? will change rear end at a later date). was told by a driveshaft specialist that a "bastard U-Joint that cannot be done ! I already have the yoke and driveshaft to fit the C4, (the correct Length). If you have made one,..... HOW ??? Thank you
