I checked on car-parts.com, I picked one up for $80 including shipping. Don't know if it is common to get them that cheap. It is a 93. I know where I can get one out of a 94 for $60, I know a guy at the yard that has it. My dad has a horror (if you caught the original typing before my edit it was good for a laugh) story about breaking one of the tube in tube shafts like the newer Mark VIII's came with though so I stayed away from it.
That is correct,you want the 93 Mark driveshaft.Like was said prior 93 is the only year that I know of for the 1 piece shaft.I am putting a Dennys Driveshaft in my 96 as soon as I take it out of my 93 Mark.Those are like 475 but I think are very light and look so well built.
out of aluminum - not actually as strong as a steel shaft
but considerably less rotating mass which elevates drive
line critical speed and it's resonance frequencies.
Read Chapter 17 of Jerry's thesis - it will clearly
explain everything you need to know about drive shaft choices.
I don't know if it's possible to install without dropping
the gas tank as that's the norm when the tranny is already
in place. It's not super hard to do, but you've got to make
sure your universal joints are referenced correctly when you
install them or you'll end up with more vibration than before.
You REALLY want one, for safety, if you plan on taking
advantage of a removed speed limiter very often.
Also can be done by taking out the rear end...my plan. So, while you are swapping the driveshaft, toss in the aluminum pumpkin with 3.73's! If you do this though keep in mind that you need to talk to Dennis and get a chip to run 3.73's to correct the shift points.
