Every billet 1350 yoke I've used in the last several years is 6" long , roller or bushing .
With the yoke properly engaged into the trans there should be no need for a longer one .
If the driveshaft is too short and you need the extra 1/2" to get the yoke into the bearing ,you're setting yourself up for other possible issues .
Besides stressing the splines ,the yoke can bind on the spline when the yoke is too far out on the shaft.
