I wanted to get you as much info as possible. Length, thread and type.
The bracket bolts are 1/4-20x 1/2 hex washer type(not flange head) with dashed lines at 12-3-9 o’clock with a J in the 6 position on the head-stamp. They are a body bolt type taper. The spoiler bolts and nuts are 10-24x5/8 hex washer type( also not flange) body bolt style with a J head-stamp; all bolts are in black phosphate. Possibly Jacobson mfg or Jupiter manufacturing.
The 10-24 nuts are Kep’s style with the captive star lock washer; galvanized or grey phosphate.
Sorry it took so long.

Slightly different question but regarding front spoilers.
I have no photos of my two previous 1974 Z/28s showing detail but is the as molded lower valance, the one with the center section molded in NOT the soft replacement one painted black on the 74's or body color? I remember them being black. And going to body color in 77 when the Z/28 came back out.
Can anyone let me know? Thanks
