A corporate 14 bolt uses 1350 series u-joint and a stock driveshaft will fit with a 5" lift but will need a combination joint (half 1330 and half 1350) or a strip of plumber's tape around the joint on the 14 bolt side (not recommended for anything long term)
Combination u-joints can often be put together at a part's store by finding two different u-joints and switching the caps.

U-Joint Info
U-joints come in a lot of different configurations and are manufactured by a lot of different companies.
Brand - For general use (both highway and heavy offroading), Warn industries has found that Spicer brand u-joints are superior to all other brands (the closest competitor was 85% the strength).
Solid Body U-Joint
Body Fitted Zerk Fitting
Capped Grease Fitting
Grease fitting configuration -
Solid u-joints without a grease fitting are the strongest, but often fail since they just don't get regreased. The seals will eventually fail and the joint will rust, squeak and then fail.
Grease fittings on the side of the u-joint are the most common setup for aftermarket u-joints and generally last longer since they can be easily regreased. Since there is a grease port in the body of the u-joint, it is weaker than the other two configurations listed here
Capped grease fitted u-joints are the better of the two above. They are much better for high impact loads than u-joints with body fitted grease fittings and can be lubricated to all for easy maintenance.
Size - bigger = better. Late model Broncos come with 1330 u-joints. 1350 are stronger and 1410 are stronger yet.
NOTE: D is the Ujoint cap diameter
E is the outside dimension across the joint from cap to cap
R is the diameter of the machined seal surface
Q is the length though the hole, and while not absolutely critical should be close o as to allow proper pinion nut tightening
S is the total "length" of the yoke, and as such, assuming Q is close, will affect driveshaft length slightly
