Thank you zfool. This info is very helpful. I will search for a supplier for these specifically and post my finding here to help anyone else that's looking to replace/install the brace bolts and front spoiler end screws.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.
