Actually it was a little long, per se. Not that it didn't fit/couldn't be installed, but just after installed and with car on ground and the suspension loaded I just wasn't comfortable with the amount of room for yoke movement along the transmission output shaft to allow for suspension movement. I actually installed it and test drove it with no problems, just was uncomfortable with what I mention. My car is lowered in front and rear so that may be a factor as is a lot if things...pinion angle etc.
I think what caused the problem, to be honest, is I also installed a Strange yoke on my 8 3/4 center section so I could use their (Strange) beefed up u-joint caps. Comparing it to the stock yoke it was a little longer so I think that was what caused the problem as I measured exactly how the Strange website order form for ordering drive shafts said to....but did the measuring with the stock center section yoke installed cuz at the time I hadn't bought their new yoke and driveshaft yet obviously.
As FYI, my car is a 70 Cuda with a 440 and A833 also. If your car is at a point to where you could check it immediately, and if you're interested, Id be glad to let you try it and if it doesn't work for you....send it back and Ill give you your money back (as long as it isn't damaged) I'd just like to get it out of my way and give someone on the site a good deal.
