I said 2.5 and 3 not knowing the exact numbers. I have one with a 2.45. and one that had the 3.09 put in it.I was thinking the 2.45 wouldnt be low enough and the 3.09 would be a large jump from 1st to second. I wised i had the 2.66 one. I would be using it.

from what i know, those 2.45 close ratio boxes can fetch a pretty penny, especially with guys doing challenger T/A or AAR cuda restos/recreations...if you sell it you should have more than enough for a 2.66 box
