thanks 2Many,...but I am using a repop.of the polyurethane 1972 lower front valence...the spoiler hardware kit is for the metal valence...on the 9422759 washer, which measures 1 1/8'' D I was able to locate a ''close enough'' 1'' D match...so if someone could look up those 2 screw part numbers, they might tell me the lengths of them...when I got my car it had a new metal valence but they were to cheap to get the spoiler...I have lots of extra GM hardware...I am guessing one of them is a 1'' thread lenghth...thankyou for the intrest!...and good news for me,after 8 weeks I did get my unemployment so I am more grounded...unfortunately I spent my new deluxe seat cover $...back to saving!

these are the screws I am trying to determine the lengths of...my original post has a wrong number listed, sorry and thanks!

Here is some printouts from the Firebird parts catalog. I found the part number you're looking for in the listing, but couldnt locate it in the illustration...

Hope that helps while I look in the 65-75 Pontiac parts catalog!

I found some of the correct washers, if you need them still.

You are right!! 45-60 SECONDS per car off the assy. line, they did NOT care, as long as it had a bolt. Have seen ( parted) many cars with different head markings on each side of the car...and thats been discussed here before to.
hardware that hits the floor? swept up and trashed, never re sorted or used...

Glenn,

Just saw your PM. Here is the printout from the parts catalog for the lower spoiler.

As you can see, its different from all the other pages. Dont know if its was added later... Its not very clear, and it doesnt show the parts number unfortunately... I dont even know if its for 72.

Hope that helps!
