Driveshaft measurement

Anybody know the length of a 6l80 driveshaft in a RCSB 2wd?

I wanna say mine measured 64.25-64.5" from flange face(rear U-joint centerline) to output housing. Later I'll go measure the old shaft, I have it stashed in the warehouse.

Just measured the original shaft at 60.25" from center to center. Thats not the same measurement I gave you before but should be fine as long as your builder uses the long 4L80 style slip yoke.

So the 4l80 and 6l80 use the same output shaft?

Same spline count and slip yoke. I only mentioned it because most 4l80s had the short yoke but our 6l80s use the long one. Wouldn't want you to use my measurements with the short yoke and waste time and money.
