you could get this pack for the ls10, i think the 2500 is just to small.
and thats a 9L in it not an 8, and good luck beaking the Ls10 its quite a challenge, search LS10 on youtube and watch the videos of that truck if you havent already. Its tough! and if your not gonna use that whole area on top of teh center diff you could trim it up a little, i had a big specktrum reciever, a cc bec and all the reciver leads bundled and ziptied dow to it. with the mm on the servo.
