68,69 Maybe 70 - 4 Blade Fan Help - Which is correct

I picked up a original factory 4 Blade Non-Air Fan and compared it to what I thought I already had but they are different and now I am confused as to what is actually factory correct. Maybe both are wrong?

I found in a parts book that the correct 4 Blade fan is #1235032 and is for 68-70 using a 4 Blade and beleive that picture "B" is this part number. But my assembly manual lists part number 1230075 as the 4 Blade fan for 69 (the assembly manual is usually correct).

Which fan is correct for my application "A" or "B" for a 69 4 Speed Non-Air - Both measure 18" but the angles are off and "A" fan is 3.5 inches wide and "B" fan is 4 inches which increases the center.

Can someone check their original fan blade and verify? Maybe they are both incorrect.
Thanks

"A" Fan


"B" Fan

 

This is what was used on a 6 cylinder 70 Lark I had.

 

Terry- I will go down to the garage on Saturday... . The 4 blade is standard equipment on a non air 69 GS 400.

Oh, it turns out I still have that bucket of bolts.. ... So, if you need anything specific, let me know.

 

All my fans look like the "B".

 

thanks George and John I was hoping it was B it's the nicer of the 2. Anybody else verify their 4 blade.

 

Any other 69 guys to verify.... got to be lots of 69 400 non-air cars out there

 

Terry- B fan.... I have pics... Definitely B fan....
