Slip Yoke

Yes, factory installed is possible since all '67 A-bodies used the small 7260 u-joint regardless of output splines, engine, etc. It just so happens that the only parts catalog that I have is a '67 which shows this. Hardly relevant here at this point but more of an FYI since you already have a 7290 driveshaft. In the picture ,the 2660669 yoke for '67 383 A-bodies is a 30 spline 7260 yoke. Too bad there is no partial vin on '67 transmissions. 67833.JPG
