Seeking Picture of Radiator Shroud Bracket 1968 with Small Block and Copper Radiator
Do you have a picture you can post of the correct bracket that attaches to the fan shroud and then to the valance in front of it? 1968 small block with copper radiator. AIM is not clear.
Still hoping someone out there has a '68 small block with a copper radiator. (Usually installed on cars with an automatic transmission OR air conditioning OR both.) Trying to figure out which shroud bracket is correct. Attached is a photo of the one I THINK is correct.
Hi N,
I believe cars with copper radiators had fiberglass shrouds not the shroud or bracket in DR's link.
I'm looking at C60, B3 and B4 in the 68 AIM.
It appears the shroud used with bb and sb engines varied, but was fiberglass.
Just what radiator, core support, and shroud are you using?
Regards,
Alan
The bracket in your photo appears to be more similar to the bracket used in 68 for the aluminum radiator's steel shroud to core support connection.
Hi,
The bracket Donnie posted DOES appear to be similar to the one DR posted.
Perhaps the same bracket was used for both the aluminum and copper shrouds?
What's shown in the AIM appears to indicate a different bracket being used?
???

Alan
Hi D,
Also, the bracket you show mounts on top of the core support while the bracket n pictured and the one in the 68 AIM shows the bracket mounting again the rear 'face' of the core support.

Do you have a picture you can post of the correct bracket that attaches to the fan shroud and then to the valance in front of it? 1968 small block with copper radiator. AIM is not clear.
I have a 1968 SB with AT and AC. The rad is copper and the shroud is metal. It is all original. I have owned the car since 5/70. I will try to take some pics on Sunday.
This page from AIM shows bracket 3914351 attaching to the support assembly (part 2 in the illustration). This is NOT the bracket I'm missing, but it appears to be the bracket to which the bracket below attaches. It looks quite similar so it gets confusing.
This is the AIM page that describes the shroud bracket for small blocks, but the illustration shows the aluminum radiator (no AC, no auto trans). The bracket I'm missing seems to be configured like part numbered '13' in this illustration. It is part #7919752. Note it has two bolts that pass through the shroud.
Finally, this is the only illustration in the AIM that shows a copper radiator. In this diagram part numbered '9' is the shroud bracket. It has a SINGLE bolt attaching to the shroud. Not the bottom of the page where it says 'air conditioning'. Maybe I just need a little education on how to read the AIM correctly.
The first sheet shows the aluminum radiator bracket #2, (it only supports the radiator), for base motor cars that are 4-speed equipped and don't have a/c.
The second sheet shows the baffle #3 and bracket #13 for attaching the steel shroud to the core support for use with aluminum radiators.
The third sheet shows the bracket #9 that bolts to the baffle #3 and bracket #13 and that secures the fiberglass shroud to the core support for use with copper radiators.
I don't understand why the 'set up' for the small block radiator/shroud isn't shown? I'll look at the AIM again to see if I can find it.
It could be that talley has the answer… in 68 small block cars with copper radiators had steel shrouds too.

That is the correct bracket for 1968s with a copper radiator. It was used on both 327 and 427 cars that had copper radiators. The bracket could be used with both the steel and fiberglass shrouds.
All 68s used a steel fan shroud at the beginning of the model year. The steel shroud could be used with both aluminum and copper radiators. The 427 engine equipped cars switched to a fiberglass shroud after about vin 2400 to help address the cooling problems they were having. I'm not sure if the SB cars with copper radiators switched or they stayed with the steel shroud to the end of the model year. It may be dependent on if you have A/C or not. I'm away from my reference information for the summer to be able to look that up.
Below is a picture of a 68 with a copper radiator and the bracket in your post.
Attached are pics from my 1968 SB with AT and AC - copper rad w/steel shroud. Build date in early Jan'68. There are two brackets. First mounts to the forward brace. It has two holes for bolts. Second bracket is L -shaped. It bolts to the first bracket. The metal shroud then bolts to the vertical portion of the L-bracket. Hope I can get the pictures attached.
Hi t,
Interesting photo!
That appears to be the set up shown on Sheet B5.
On it the bracket is called out as item #13.
2 brackets required to reach OVER the copper radiator to secure the steel shroud to the core support!
Thanks for taking the time top post it!!

Alan
Wow! Thanks, guys. This is VERY HELPFUL. Now we know and the answer will be forever enshrined here. I think GM included a LOT of brackets.
And now I get to make one of these. That will take a while. Talley, at some point could you tell me the length of the bracket from where it attaches to the shroud to the forward edge? I think with that measurement, your photo and my car I can determine the other dimensions.

Thanks again!
Consider these measurements to be reasonably accurate. Good Luck.
How "accurate" is your restoration? I spent a year looking for a correct one for my 68 cause I wasnt going to pay the guy with the one on ebay $499 for a $50 dollar bracket. I also found that one from a 1969 will functionally do the same exact same thing. If you are not going NCRS, no need to go crazy.
Repops are $15 from the usual corvette vendors.

Awesome, T thank you! B my car is VERY original and I slowly work to restore the things that aren't. Thank you for the bracket pictures. And you are right, the cost of the originals is obscene.
