Very cool item. Are the metallic brake shoes and special brake springs still present?

I will have to check, I figured the shoes might be there as they take forever wear out.

The rear was out of AZ and is very nice shape. I am assuming it would have been in a 67 SS 350.

Must be early. No traction bar? Maybe early z car. 3:31 road racing rear?

[1967Z28]

This would have been out of an SS350. It's too early for a Z and even the very first Z-28s had the traction bar.

Do you have any info or knowledge as to the front brakes associated with this rear end ?

Pretty tight casting to assembly date too.

They would have been metallic front drums with this early date and no traction bar, so this SS350 would have had the J65 metallic brake option.

[x77-69z28]

According to the original owner of my 67RS/SS, the car had to go back to the dealer to have the traction bar attached. 12D production date. If I remember correctly, it was a November casting 12 bolt.

I was thinking that.....
J56 option superceded front Power Discs on '67's or just the early ones ?

At Carlisle 2 years ago I sold a rear set of used metallic shoes with GM stamps in ink and punch stamps to a fella for a Z/28.

Nice to know there are real Metallic Brake stuff still out there for First Gen Camaros

The J56 was only 67 Z28 only and it had Front discs and rear metallic drums. Jon Mello had a survivor Mountain Green J56 equipped 67 Z28. The J56 front brakes had heat insulators behind the pucks in the calipers I am not sure if they were twin pin calipers or if they were single pin, I do know many Trans Am cars were converted to twin pins.

J65 was 4 wheel metallic drums. There were only 1217 J65 cars.



DATE IS ~ J 17 6 October 17 1966.

would the 3.31 gear have been a desirable ratio for any kind of track racing in that era?
