I had to have one made for mine with the exact same setup. They told me at the drive shaft shop that I would have to install the transmission and then measure the distance between the transmission and the rear end ( u- joint to u-joint ). It's my only vehicle so that really wasn't an option for me. I subtracted the length of the 4 speed from the length of the 3 speed transmission and added that to the length of the distance between the rear u-joint and the point where the front u-joint would be if it was secured solid to the transmission like on the 4 speed. It took some figuring and I was sweating over it but in the end, they built me a slip shaft that bolted right up. If you can't just measure the distance after you install your transmission and wait on the drive shaft to be built, it isn't that hard to figure it out mathematically. You do have a little bit of wiggle room since it is a slip shaft.
