I gave a set of early s10 16x8 ZQ8 wheels. Look the same as 91-92 z28 wheels but all 4 are the same offset -6.4mm. One of the four has curb rash all the way around but not deep, one has a couple spots of light curb rash, other 2 are clean. Paint and clear coat is all good, no corrosion. Includes 3 GMC center caps and 2 bowtie center caps. Although these look the same as the Camaro wheels, Camaro center caps will NOT fit-the clips that hold the cap to the wheel are about a 1/4" smaller circle on the Camaro caps. Fits G bodies and 1st/2nd gens too. $200 Local pickup preferred, but I could ship if you want to pay it. PM me here or email kgw31 at comcast dot net

Are these the offset that fit the front or back of the 3rd gens?

Third gen 16" wheels are +16mm offset on the rear and 0 offset on the front. These will fit front and rear on 3rd gens.

Hmm...I guess that doesn't answer my question completely, my cousin wants this style wheel for his '77 Vette and only the front wheels from a 3rd gen fit all four corners on the Vette. We tried putting my stock rear wheels on there and they don't work at all, but the fronts work at all 4 corners.

Actually I gave you enough info to answer your question and more. Stock 3rd gen front wheels are -0-mm offset. these are -6.4mm(1/4") offset. These wheels will stick out 1/4" more than stock 3rd gen front wheels.

I am not good with understanding backspacing numbers, but when it's a -6.4mm does that mean that the backing on the wheels sits 6.4mm closer to the backing plates on the car, or 6.4mm closer to the outer edge of the rim on the wheel?

It's a confusing system. When the offset is zero like a 3rd gen front wheel, it means that the mounting surface of the wheel (where it touches the brakes) is centered on the rim-an equal distance from both the inner and outer bead seats. A 3rg gen rear wheel is +16mm offset, meaning that the outer rim is shifted 16mm inwards relative to the mounting surface, and would make the track width of the car 32mm narrower. It makes the inner edge of the rim 16mm closer to the LCA's or tie rods ect. These wheels are -6.4mm so the outer rim is moved out 6.4mm relative to the mounting surface, making the track width 12.8mm wider, and moving the inner edge of the rim 6.4mm farther away from the suspension components.

Oh ok well that makes sense to me. So these will stick out farther than stock FRONT 3rd gens, I am pretty sure I have a buyer for you. He's picking up his son from school right now and I'm going over to his house to show him this ad when he gets home and I'll let you know for sure. We're down here in the St Louis area, not really too far from you.

Bumping this up-still available.
