Mancini Racing still selling Yukon axles that are 3/8"-1/2" too long

i bought a set from mancini last year for my a body ,talk about a confusing mess they are. i did convert to big bolt pattern and put on 2.5 brakes ,but my shafts wouldnt even go into the rear.they were splined sloppy.had to use emery cloth on them then they didnt drill the studs for me so had to take them somewhere spend another $60.so they told me i needed 28 inch length they were 1/2 inch short when they came.i went round and round with them,i wont buy a spark plug from them.
