Drive shaft length specs

Earlier this year I needed to shorten my driveshaft after putting in an 8.75 to replace the noisy 7.25. I did some measuring and decided it needed to be shortened about 2".

While looking through my factory shop manual I discovered they had the driveshaft dimensions listed for all the various transmission/axle combinations. The book confirmed my measurements and said that it needed to be cut just a fraction over 2". It was actually listed in thousands, not fractions, but I don't remember the actual number right now.

So check out your OE shop manual. It just might have the info you're looking for.
