You are looking at the drive shaft from a 72 Pontiac Grand Prix with TH400. It is 55 5/16” from center of bearing cap to center of bearing cap, 56 ¾” from loop to loop. It would measure 61 1/4” total if it had the yoke. Drive shaft is correct length for the following cars per the Hollander Interchange:

68 to 71 Grand Prix w/ large output Muncie 4 speed or TH400

68 to 72 Pontiac Lemans & GTO w/ large output Muncie 4 speed or TH400

May also fit Olds 442 or Buick GS. MEASURE YOUR OWN NEEDS BEFORE BUYING. The U-joints should be replaced due to age. Nice & straight. No dings. Hard to find.
