Help identifying an A-mold wheel

[rgfllamas]

Craigslist was good to me!

I responded to an ad for a set of 5 spoke wheels that fit a '98 to '02 Camaro. 11 inch rears and 9.5 fronts. Asked the fellow if he had any numbers off the backside of the rims and the only thing he sent back was 10214047, yup real ZR-1 rears. Made the trip to see them and indeed the backs are original GM ZR-1 A-molds, dirty and a little marked up but not too bad for a 20 year old wheel. Fronts weren't 9.5 inch but he wouldn't split up the fronts and rears so I had to take it all. All four are silver painted.

The fronts are not 9.5 inch, they're 9 and I am unsure what they are off of.

Here's the casting info from the backside of the spokes:
Spoke 1: UM 1 or LM 1
Spoke 2: JPN
Spoke 3: 17x9J 50
Spoke 4: looks like a casting clock
Spoke 5: another casting clock
front side does have the JWL marking

'96 CE vettes used 8.5 amd 9.5 inch and I think Camaro's used 16" wheels.

If my calculations are right, even though this rim is 0.5 inches (12mm) narrower than the original fronts, the 50mm offset vs. the original 56 would put the outer edge of the tire in almost exactly the same spot on the car. I know from a purists stand point it's not the correct rim but I've got a '91, so even the correct rim would be wrong.

Anybody know what I've got?

Any thoughts on using them? They are a perfect match in appearance to the rears.

Sounds like a Camaro SS wheel they were 17"X 9"

96-99. Y2K brought out a new wheel design.

96 Verts had a 16" version of the 5 spoke. 97 verts got the full 17".

OK,

Looks like 97 to 99 Camaro SS. Thanks, to all that responded. Are they common?

What are your thoughts about using them? They gotta be a decent wheel, from what I can see they're constructed exactly the same as the rears. Should be relatively light weight yet strong. Is my math correct? Does the outside edge of this end up in almost exactly the same place as a 9.5 with the 56mm offset.?
Can anyone tell the difference between a 9 and a 9.5 once they're on the car (without measuring)? Obviously I've got these and I'm trying to decide if I should be considering investing in 9.5inch or going with what I have. I guess tire size would also come into play in what the final result would look like.

Thanks
