That’s standard length. Like I said, since you have to buy a new tube (and the yokes) I would upgrade to at least a 3 inch tube and 1350 ujoints. You are already buying a new slip yoke, so why not buy a 1350 sized one? The only extra cost is for the 1350 flange on the pinion.
I am from the school that you can’t get the driveline and ujoints too big.
