66 67 AC tubes through rad support

[Craig O.]

what side of the radiator core support does the grommet with the 3 tabs that is used in the holes for the drier and condenser tube go?

Passenger side, unless I'm missing something here.

Kirk,

I think he means do the gaskets install from the rear side of the radiator support, or do they install from the front side. The AIM seems to show them installed on the front side, with the steel prongs inside the rubber gasket presumably then being bent outward, securing the front-mounted gaskets to the back side of the radiator support.

But the AIM may show it that way for ease of illustration, or the AIM could just be wrong. There is a depression on the back side of the radiator support at the uppermost round hole on the passenger side, that suggests the uppermost grommet might install (i.e., be seated into the depression) on the rear side of the radiator support. The "depression" is the result of a double thickness of steel with the hole cut a little larger on the back side than the front side.

The 66JG describes the grommet (p. 147) and so does the 67JG (p. 92), but neither says whether the grommets are installed from the front or the rear.


Or, Craig could mean something else entirely

Exactly Scott, my AIM is an old copy and can't make out placement,
If I were to guess I would install them at the front and bend the tabs at the rear. someone will check theirs I'm sure, Thanks, Craig

Re: 66 67 AC tubes through rad support

My grommets were installed with the rubber on the front side of the support and the tabs bent on the inside of the support. Until recently the least time that they were touched was in the 70's.

Hi Craig,

I purchased my '66 L-36 AC convertible back in the late 80's. The lower grommet for the dryer tube was installed from the front side of the support. My car was built late November '65 and the tube that connects to the condenser ran over top of the support and not through it. So, there was no grommet installed in the upper support hole.

Mike,

I found the following picture in the archives, it's a 1966 small block with C60, St. Louis body, built late September 1965. It has the condenser tube going over the top like you describe, with the drier tube going through the radiator support, but the grommet on this example is attached to the back side.

Does anyone know if this is a case where either installation (front side or back side) was typical factory production? Was installation of the grommets the same for 1966-1967, once the change was made during the 1966 model year to the radiator support with two holes, and both tubes were being routed through the radiator support?

Re: 66 67 AC tubes through rad support

Craig, I left the grommets on the lines when I removed them during the disassembly phase of my restoration so I could re-install them correctly (I also have pics, but unable to post them). I'm 2nd owner of a woman 1 owner car. I'll check when I get back home on Thurs. and let you know. Al

Re: 66 67 AC tubes through rad support

Hi Craig, update on the A/C line grommets on my car. They were both installed from the engine side with the tabs being on the bumper side. It appeared that the lines had never been removed as they were still the original ones along with all other components of the system except the compressor which was replaced under warranty according to the original owner. Hope this helps! Maybe others with orig. cars will check theirs and let us know!! Come-on guys Help out Craig!

This photo is from a 1967 327/300 air condition 5 star bowtie car which agrees with Al's installion of the grommets.

Re: 66 67 AC tubes through rad support

Just checked 67 S/N 1476 base mtr w/C60 and the the A/C line grommets are installed per Page's photo and Al's information, i.e., from the engine compartment side w/the tabs toward the front of the car. Pete

I will report on 7471 tomorrow.

Re: 66 67 AC tubes through rad support

S/N 7471 agree's with this configuration.

Thanks to all for taking the time to check. Craig

Re: 66 67 AC tubes through rad support

For those with a 68 & A/C good luck on finding this grommet, it's not round like 67 but oval and very hard to find. It goes in from the engine side with clips to front also, AIM C60,B1.
