The 88-92 all used the 275 40 17s. In 93 the staggered wheels started with the 8.5 front and 9.5 rear wheels. The Z07 and Z51 would continue to use the square set up. ZL1 used staggered 9.5 and 11 inch wheels
. Z07 has the ride control switch on console. SPID label will have all option, make sure vin on label matches vin on car.

Another option not exclusive to anything. As said, see what's listed on SPI Decal.

Vins match. So I'm guessing not zo7 but has all stuff zo7 has?? At least I think so based on what I have found and also on another thread someone had posted all 91 6 speeds were zo7s with the exception of 1 automatic.
