02 Z71

so, i got an s-10, and wanna get a 02 z71 5.3. anyone know what gears they have in the back? do they have a sun roof option? how big are the tires on a z71? auto-trac or instra trac? what would be the best way to go with this? and on top of that , id planned on doing the corvette servo mod , and ddient know weather i should put the hyper tec shift firmness or go with a trans- go shift kit. thanks guys

heres some help but not much
for the gears it should have the factory 3:73's or an option of the 4:10's.
for the sun roof i do not see why they would not have the option of one in it it's just a matter of finding one with one in it.
for the tires they should be 245/70 r16 or maybe 265/70 r16 not sure on that one so dont quote me
for the auto trc or the insta trac...sry but i dont know the difference between them.

hope this helps you.
