Fan Shroud Upper Bracket
« on: June 12, 2022, 11:15:56 PM »
Couple Camaro buddies and I were discussing upper brackets and the question came up.  When or did production transition to the clip nut from the fixed nut.


Please provide production date, plant & engine option.  We can get more detailed from there if the data shows anything more.


Photo 1 is the 2 versions side by side.

Photo 2 - 68 12D LOS small block

Photo 3 - 68 03D NOR big block

I realize 69 big block is a different bracket so just looking for 69 small block photos in this discussion.

Both 68's 06a Nor 396 and 06b Nor 327 nut type. Also checked in 1969 partsbook and 67,68 and 69 assembly manuals two different part #s. 3893831 67-68. 3938612 69. 67-68 assembly manuals look like nut! 69 not good picture might be clip nut. Maybe some one with a 69 might confirm.

Thanks gentlemen. Great info & keep it coming as it appears from Sportís searching on part numbers that 69 was the changeover.  Would like to confirm when.  Thanks!

Interesting Buddy.  Thanks for the info!  We need more data points; so guys, when you have a chance buzz that bolt out and slide that shroud back a little and take a peak and report please.
