Tip to tip counting the yolk it's 52"

By this description I'd guess you have the RV type that uses a 2 piece driveshaft and has a short output shaft with a yoke bolted directly to it and possibly a transfer case or some other gear box also bolted to it and maybe even a parking brake assy. Not a slip yoke style output shaft like a car uses. Correct? If so it won't work in your car unless you completely disassemble it and replace the output shaft and extension housing assy. with car/light truck parts. The output shaft comes out through the front, that's why it has to be completely disassembled to shange it.
