I guess it depends who you talk to. I measured 64.25" from u-joint to u-joint. When I talked to the guy at the local shop that makes up custom driveshafts, he recommended that I use a two piece driveshaft. I followed his recommendation.

My Dad's 63 Chevy long box step side had a two piece driveshaft. I remember the steady bearing failing on the Alaska highway. What a PITA!

My 1980 3/4 ton long box had a two piece driveshaft. No issues with the steady bearing.

My 2010 1/2 ton long box has a one piece driveshaft. It looks like a big aluminum sewer pipe!
