If you ever wanted to know the size of factory U-Nuts
Here you go. Spent WAY more time measuring than a person should, ("damn your eyes"......"too late"). Anyway, should be right and feel free to correct.
At some point this list will be a mile long. Get to inventory the parts (fun) before I have them phosphate coated or zinc plated. I just went through the U-Nuts to see if I can buy matching new. THIS HAS BEEN UPDATED. Picture was gone, so added this instead. Placement & Part / Description / Thread size FAN SHROUD U-NUTS U-NUTS - 3/4 (W) X 5/8 (L), WITH A 7/32 CENTER HOLE TO EDGE 1/4 MARKER LIGHT U-NUTS U-NUTS - 1/2 X 5/8, WITH A 1/4 CENTER HOLE TO EDGE #8 TAIL & REVERSE HOUSINGS J-NUTS J-NUTS - 1/2 X 5/8, WITH A 3/8 CENTER HOLE TO EDGE #10 HEADLIGHT BEZEL J-NUTS J-NUTS - 7/16 (W) X 21/32 (L), WITH A 3/8 CENTER HOLE TO EDGE #8 GRILLE U-NUT U-NUT - 5/8 (W) X 1 (L), WITH A 9/16 CENTER HOLE TO EDGE 5/16-18 GRILLE U-NUTS U-NUTS - 7/16 (W) X 11/16 (L), WITH A 3/8 CENTER HOLE TO EDGE 1/4 GRILLE U-NUT U-NUT - 3/4 (W) X 11/16 (L), WITH A 3/8 CENTER HOLE TO EDGE 1/4 A/C VENTS (outer vents) J-NUTS - 7/16 (W) X 9/16 (L), WITH A 3/8 CENTER HOLE TO EDGE #8 COWL PANEL J-NUTS J-NUTS - 1/2 (W) X 5/8 (L), WITH A 1/2 CENTER HOLE TO EDGE #10 INNER FENDER U-NUTS 21/32 (W) X 1 (L), WITH A 9/16 CENTER HOLE TO EDGE.

Re: If you ever wanted to know the size of factory U-Nuts
thanks, I already saved it. I try to bag & tag everything & take pictures but when I go to put it together the picture never shows exactly what I need to see.

Re: If you ever wanted to know the size of factory U-Nuts

Here is the "U" nut size for the '72 only door stiffener screw below the wing window.(2 needed, one for each side) #10 screw, hole center 7/16" from outer edge. You can add it to the chart if you want. Edit: The instrument cluster "U" nuts are exactly the same as the dash pad "U" nuts.... LockDoc

![]() Sure will be a lot easier to measure with the digital gauge pending receipt. Anyway, I've updated the chart with a few more U-Nuts. Can't think of any more. Thanks

Re: If you ever wanted to know the size of factory U-Nuts
Yep, pictures only have some value. I prefer to put everything into words, which is tricky, because what you write today may be meaningless tomorrow.
These may be the most common #8. No sign of width or length but that should be OK, I think. I've asked the company to clarify how the "Center Hole To Edge" is measured, but I think it's right. Good company, just discovered them. https://www.fastenal.com/products/details/0162858 This MIGHT be close to the original J-Clip that mounts to the E-Brake on the firewall for the LH harness. I don't have the patience to match the way they measure this stuff, but for the price what the heck. It's nylon coated. The originals are rubber coated. Close enough. https://www.fastenal.com/products/details/0709204 I figure the thread cutting nuts for the Dash Pad are between these two or both, because the two studs on the outside appear larger than the other five. That said, I need 200 of these like a hole in the head, but for twice the costish you get 20x the pieces: https://www.fastenal.com/products?te...32&searchMode= https://www.fastenal.com/products/details/0162828 Marker lights I'm guessing. Looks similar if not identical. Their Center to Edge measure is approx. 7/10ths a millimeter shorter than my measurement, assuming I'm measuring right. Real close. I don't need them, the originals look great and they're easy to finish. https://www.fastenal.com/products/details/11120280
