Honestly, I would pass on the Friuls unless you want to depict a broken track. The Stuart, along with the rest of the same period US tanks, used a "live" track design which only showed sag when it was well past replacement time. Some pics of Lend-Lease Soviet M4A2/76 tanksiin Austria and Berlin show their T-49 tracks sagging, and there's a pic or two out there showing US M3 Lees in North Africa with their rubber-block tracks with some very slight sag, but it's not normal.
I have Tamiya's new Stuart on the bench right now, and barring 6 sink marks on the inside of a pad on each run, look very good and should represent the actual item very nicely. I'm a stickler for tracks, and these will be used by me.
