brand new never used. Just taken out of package, everything is still there. $25 plus shipping.

Will this work for a 4th gen? Weld on only? If this will work for my application, consider it sold.

I have no idea if it will fit a 4th gen, I don't own one.

Will this fit a third gen? I believe they have the same shaft. Is this a weld on unit?

I bought this years ago from a part number listed here. It did not fit my thirdgen shaft like I thought it would, but it was close. I could have turned a bushing to make it perfect. I've never installed one of these, so I'm not sure how they are supposed to fit, I ended up not needing it in my Camaro and it's been sitting on the shelf.

Yes this is a weld-on piece, apparently you didnt read the link I posted?

If Batman doesn't want it, let me know. I'll have to weld something on anyway, and this will save me some cash..... PM me
