I recently purchased a all matching numbers 1968 Camaro RS SS 396 and am not sure if it has the original carburetor.

Its the Rochester Quadrajet and the only numbers i can see are on the back of the carb 7035530 in a circle and J27.
There are no numbers on the round metal disk or stamped into the vertical boss on the driver's side main body.

Can anyone tell me if this is an original for the 1968 Camaro?

 

If I'm reading the information on the attached pdf correctly, this is off a 1975 Cadillac with California smog and an automatic transmission. From what I understand, if it was off a 1968 model year car, the fourth digit would been have an "8".

 

Thank you! looks like i need a Carb coded 70385(0,1,2)(0, 2, 3, 8, 5) to be matching.
