Driveshaft questions?

[GMT400 STEVE]

What's up guys, I was wondering if anyone could give me the length of a rear Driveshaft. I have a 1995 k2500, 4l80e, 4x4, extended cab long bed. 155.5 wheelbase. 5.7l. Thanks!

Is the 2500 a piece drive shaft? If it is I can crawl under my truck later on and measure. I have a 14 bolt FF rear.
