hey guys, hard to think at 41 that i'm a newbe at anything but i've always believed ask for help when it's needed. so here's the question ; i've ordered the grs 2 and have a set of axles with 513's and 33x9.5 . what i'm looking for is advice on wether i should switch to 462 or not , or maybe go with stock 391 (oh yeah it's a lwbwith a 1300) and 31" or 32" tires. i'm also intrested in what kind of final speed to rpm i might end up at. this is my daily driver and i'm not using it for a rock crawler , more to take the kid and the dog camping and fishing and get in and out of some tight spaces. thanks in advance.........jeff
