Damn-it Carl! That ain't gonna work!

Those look like Cliffords for a 67 or newer vehicle. The Clifford "long tubes" for a 65 down look like the ones in post #4. To the best of my knowledge the long tubes never had a "fit auto or fit standard trans" difference. As Rusty said. Also Before the days of the "shorties", Clifford had about 8 or 9 (would have to check my old catalog) different variations of long tubes for different applications.
