You are looking at the drive shaft from a 70 Pontiac Lemans coupe with 350 & TH350. It is 56” from center of bearing cap to center of bearing cap, 57 1/2 from outside loop to outside loop or 61 1/8 total length including yoke. Drive shaft is correct length for the following cars per the Hollander Interchange:

68 GS400 w/ Muncie 4 speed

68 to 69 Skylark w/ ST300 AT

69 to 70 Grand Prix w/ Muncie 4 speed

68 to 69 Olds Cutlass & 442 w/ Muncie 4 speed or Jetaway (2sp) AT

68 to 72 Pontiac Lemans & GTO w/ Muncie 4 speed or 2SP AT or TH350

MEASURE YOUR OWN NEEDS BEFORE BUYING. Yoke is 27 spline and will fit 3 speed, or pre 70 Muncie M20 M21 and M22 4 speed, Power Glide or TH350. The U-joints should be replaced due to age. No heavy pitting. Nice & straight. Hard to find.

 Alot of people think getting the driveshaft is one of the first things you do in a build. It is actually one of the last things you do. I am currently rebuilding my 66 Biscayne with a 632 and a 5 speed. I am having a custom driveshaft made. Before I can establish my length, I need to have the car done, at full weight, sitting at my determined ride height with the weight of the car on all 4 wheels. Then set the pinion angle on my rear. Then measure my needs allowing 5/8" to 3/4" of yoke to stick out the back of the transmission. While I am not saying you must go through all this effort to determine you required length, I am saying make sure this is the length you need. I list the measurements in my description. I hope this is the correct length for you. Thank you for your interest, Dave.
