well I bought a 10 bolt none posi rearend for my 67 firebird .
thinking that it would fit with no problem . well there was ,,,,
The firebird;s rearend had just one difference , that it has a stock welding of were you mount the traction bar to . That part is welded on both sides of the firebird .. But the 67 camaro rearend does not have that at all ... its straight with no sign of welding to
the axel for traction bar ...

Can anyone tell me if the 67 firebird came this way stock ,,, and

why dident this come in 67 camaro ... ? thnks

Both cars came down the same assembly line. The traction bar mount was probably added by a previous owner. A traction bar of sorts was offered by the factory, but as I recall only mounted on one side to control wheel hop, which these cars were famous for.

Hi,

On '67 Camaros with hipo engines and 12-bolt rearends, such as the SS 350 and the SS 396, a radius rod was mounted to the rear end and to the floorpan on the passenger side. You can read all about it at http://www.camaros.org/radiusrod.shtml if you're interested.

Early Camaro's like mine (January '67) came with the round rod and later models (after April '67) came with a square rod.

As Bobcrman said, it was a bandaid fix for wheelhop on those cars. Chevrolet went to multileaf springs and staggered the shock absorbers on the 68 and later cars as a more effective means of controlling wheel hop.

The 67 Firebirds with hi output engines came with a similar setup, only the traction bars were on both sides. Unique to Ponticac.

Do you have to have it? Probably not if you install some slapper bars or some other traction control device.

Hope this helps.
