i would take that as the shaft is the same from LA to MAG...and i can't see you having a problem dropping it in, as i have 100 times.

worst case scenario, put a small taper on the end, and grease it.

thats about all the help i can be.lol I went straight from LA's to 5.7 Hemi's...so i have never torn down a mag engine.
