I think not, but here goes.  Is there any differences in the radiator core support be it an a/c or non a/c camaro?  Differences in the yrs. for the support?  Radiator hole opening size?  I know the mounting holes are different for SB and BB radiators.

the only thing i noticed was a panel that bolted on between the core support and the fender on A/C cars. i've never owned a BB car.

Here's what I know.

69s are unique, having holes along the front of the top rail to mount the condenser.

67s & 68s have larger holes to mount the voltage regulator. It was mounted on rubber nut-serts. 69s mount directly on the support.

There is no differerence between engines. There were 2 pair of mounting holes on the left side to accomodate both bb and sb radiator mounting. It is possible early 67s do not have the bb holes.

OE supports are smooth across the top. GM service replacements were quite wrinkled.

There may be other small differences. They all seem to interchange.

William is correct of course Smiley I can add: pre 69 versions had dimples for the AC core/hood seal, earlier ones did not, but I dont know the cutoff.

Those holes were a running change, implemented in January 69, IIRC. My 01B car doesn' t have them.

Some notes to add from my research.  Early 69s used the 68 style voltage regulator mount with rubber insulators, screws and ground wire.  I think the screws mounting the regulator right to the core support started about Jan 69.

Also, C60 AC hole provisions were added at the beginning of the year according to my data.  They were needed to mount the AC condersor on 69 models.  If these holes were not there, how would you mount the condensor?  Totally different AC system from the 68 model year.

Thanks Jerry!  I wish I had known that earlier Smiley  I swapped a core support for my 10B 69 car and I welded up the reg holes so I could use the screws, now I have to drill them out again Cheesy
