71 front bumper bolts
Checked my AIM UPC 14 sheet A3 it shows bolt item 13, lock washer item12 and shim item 15 change 2. Also, shown was item 14 which doesn't look like my bracket(my brkt is approx. 1 1/2 inches wide and I do not see a reinforcement ext. as called out on drawing. Anyway what I want to know is what size is the bolt and are the shims fabric or metal and what thickness??
thanks Mike
There are actually 2 brackets used for the side bolt on the front bumper.
One connects to the back of the bumper and one links the large side bumper bracket to the small bracket I just described.
Here you see the end of the bumper bracket, the small bracket reaching forward to the small bracket mounted on the bumper and the bolt running through the bracket to the bumper corner. This is the left side looking up from below.
The bolt is similar to the other bolts…7/16"x14x1-1/4". Not all cars used shims and I'm not sure what was used when something was needed.
Be careful working with these corner brackets and bolts…. it's very easy to crack the fiberglass.

Alan

thanks for the heads-up. Your pic shows the twisted bracket that I'm missing. I'm sure one of the vendors sell. Your correct! Some paint has rubbed off from the bumper vibrating.
thanks

The bolt that attaches the Corner reinforcement to the bumper extension and then thru the body and to the bumper itself is 7/16 ,14, 1 1/4. What is the size of the bolt that attaches it to the nose piece?
Thank you,
Kyle
