If the fronts are short ones similar to the height of the rears on this frame, then it's probably NT.
It is my understanding that all CJ-5's were build with NT axles. It would always be possible that Jeep could have run out of NT axles and substituted WT axles at the end of the production run, but given the publicity and controversy at the time about the CJ-5's stability, I'd find it hard to believe that Jeep would have made any changes to the suspension in the last production year. Making that change would have been like an admission that the CJ-5 was unstable and could have been used against them in lawsuits.
But with Jeep, anything is possible
Never say never about anything "standard" Jeep.
True! My 5 is narrow track, but has the tall front shock mounts.
The bottom shock mounts on the front are on the axle not the spring plate.
But my 5 is assembled from parts. I think I have an 82or3 frame and front axle, 79 tub, and a 78 rear. Go Figure!
