Which 14 bolt 10.5” ff can I use on my 2000 Chevy Silverado 1500 z71? What type of vehicle would I pull it from?

Hi community, seems like there is alot of information out there about the various GM 14 bolt axles, how to try and ID them from the outside and what model year/trim trucks have what. I have a 2014 GMC Sierra 2500 crew cab, standard bed, Z71 with a 6.0 gas. I know most of these come with 4.10s but the RPO code (GT4) exsists on my tuck indicating it has 3.73s. Funny enough the RPO references online seem a bit out of order as my truck has the L96 code which according to some indicates I have a 2.0L I4 lol. So I’m going to re-gear and ditch the G80 for a truetrac. To my knowledge there are no RPO codes that tell you weither you have a 10.5 or 11.5aam axle? Anyone have any insight as to which I have or how to find out without taking the diff cover off and measuring? I know you can take it to a dealer and they will tell you but they also told me the truck had 4.10s when I brought it to them after I bought it used from a CarMax. Also pretty sure upfront I have a GM 9.25 unless anyone knows better?
