Default 69 Fan Shroud Mounting

I have a 69 with an L46/manual transmission. Anyone have pictures on how the steel fan shroud mounts to the crossmember? I don't see brackets or holes to mount brackest on th crossmember so I'm wondering what happened.
thanks, John

Hi John,
The steel shroud is held in place with a separate bracket at its top, 2 bolts into the shroud and 2 bolts into the core support.
And the bottom of the shroud should have 2 'tab's that point straight down, each about 1" wide and 3" long.
There are 2 small brackets (3"-4") that run from the 'tabs' to the lip on the crossmember directly below the shroud.
Does your shroud have the 'tabs' and do you have the 2 brackets?
Regards,
Alan

Hi John,
This is my 71 shroud and brackets…69 shroud looks to be the same, but brackets might be different.
Here are the 2 tabs with the brackets in place.
There is a right and left bracket, (they only fit one way).
The brackets are stamped with a part number so you can tell which is the right side and left side bracket.
Remember all right side part numbers end in an even digit and all left side part numbers end in an odd digit.
Regards,
Alan

John: the 69 assembly instruction manual (AIM) would help you with your car.

Hey Alan, thanks for replying. I think that the previous of my car owner put a copper radiator in with a plastic shroud. Since the radiator needs replacing I'm going back to the original aluminum radiator and steel shroud. I can get a used steel shroud with the tabs welded on as shown in the picture you supplied and I can also get the brackets but I don't see holes on the crossmember to mount the brackets? That's why I'm looking for a photo of how those brackets attach to the crossmember. Maybe I need to drill holes in the crossmember lip but if my frame is original that does not seem right? I'm confused and don't want to order the wrong parts.
Thanks,
John

Mike- thanks so much for the info. I have the manual but my confusion is that there is no place on my crossmember to attach the lower shroud brackets. Maybe 69 did not have the brackets and it was added in 1970.

Hi John,
Based on the AIM page Mike posted it appears the 69 bracket configuration may be different????
Here's the 2 holes on my 71 frame. They're on the front lip of the forward crossmember.
I'll be curious to see what you find on your 69 frame.
Regards,
Alan

Crossmember


Right side hole


Left side hole

Alan- thaks so much, perfect pictures. My frame does not have those holes on the crossmember for the shroud brackets. My build date is P14, late 69 so I guess I'll need to do some more invsetigation here. Thanks again.
John

For what it's worth, my 69' L-46 4-Speed car (no A/C) came with the copper radiator and plastic shroud-
Are you sure your car originally came with the aluminum radiator and steel shroud?

John: Check page 256 of your AIM. The slots that you're looking for are in a sheet metal piece identified as "Baffle - Rad Lower" (Item 5). You may be missing that part. Also, my understanding is that all 69 base and L46's w/4spd w/o AC came with the Harrison aluminum radiator and metal shroud. My 69 L46 w/4spd w/o AC has a metal shroud (but came with a replacement copper radiator). Does your rad support have the two lower brackets that support the aluminum radiator? Page 256 shows the the brackets in question.

Hi- I have the same power train, L46/manual/no A/C. My AIM manual and NCRS Technical Information Manual & Judging Guide both seem to indicate it should be an aluminum radiator/steel shroud, aluminum expansion tank. Is it possible that the NCRS manual is incorrect?

Based on the pictures supplied by Alan in this thread the mounting holesa are in the crossmember but I don't have them in my car. Do you?

Hi Paul,
I've driven it less than 100 miles since it's been restored.
However the odometer shows a little over 46,000 miles and most of those
I put on it in 1971 and 1972.
So do those count?
Regards,
Alan

Hi John,
The new 68-69 NCRS TIM&JG says 69 350HP without A/C could be either Copper or Aluminum. Rich Bizzocos book also discusses 69 L46 with copper radiators. My late production 69 L46 has the copper radiator. The problem today is no one is reproducing a correct copper radiator for this application. You could have yours recored.

Yep. 68 and 69 brackets are slightly different from later cars. Nothing more than a pair of Ls.

Wow- really interesting. I have a few questions for you if you don't mind:
1) The NCRS manual I have says third edition. Which edition do you have? Can you post me a picture of the page that describes it?
2) I've never heard of the Rich Bizzocos book, is it avaliable online?
3) The Copper radiator that paragon sells won't fit?
