THIS---------- With it all together, sitting on the ground. take measurements to driveshaft builder w/ info on how u measured it. do it once-do it right. If in doubt on how to measure it, ask the guy that will be building it, how to measure it.
True. They did mass produce them and they all (or mostly all) worked OK. But think about a few things. First, If you got ten answers from ten people on the right driveshaft length, you'd probably get ten different answers. Hard to tell which cars have prior accident damage that might not have been straightened out properly. Hard to tell how a motor is mounted (or if the motor mounts were off a bit due to poor Chinese quality. There are probably a lot of other factors that could cause measurements to vary from car to car today, but 50 years ago, on the assembly line, Ma Mopar had the advantage of having brand new cars rolling down the assembly line that pretty much had to be straight and true.
Wouldn`t these cars be kick *** if they had been computer controlled and designed , when built ??
-- The key is, that the front yoke / tube must be into the transmission, with enough end clearance to prevent the drive shaft from binding, as the suspension moves. -- The info below is from The Denny's Drive Shaft website.
Lol, yeah. Doing collision work on late models with Car-O-Liner frame and measuring equipment that's accurate to +/- 1mm. On cars with no door or hood hinge adjustments, and no alignment adjustments other then toe where everything has to be spot on, and always chasing that zero on the measurements. Then go out there and work on mine and the right apron is welded on 3/16's longer then the left, the core support is welded on the frame rails 3/16 or so over to the left, the A pillars seem to be off 1/4 side to side. Good thing thing the square adjustment holes are big enough to move the door east to west coast. The under cab measurements are not square. Length is good but I think the right rear rail is in the car a touch toward centerline. The front mounts for the leafs are off side to side. I stopped measuring it was making me nuts. Still chasing the zero on the measurements lol I wouldn't have been a bodyman very long building stuff like that.
Mine is really close everywhere, but had to shim the rearend 1/8" on one side to get it square. all body gaps are closer than the new one I bought in 1968. WHO knows ?
THE SOLID ANSWER IS: PUT IT TOGETHER AND W/ IT SETTING ON THE TIRES, MEASURE IT, AND HAVE ONE BUILT !
