Trying to identify and source the shoulder bolts that attach the storage tray to the back of the car.

Re: 1969 (early) Rear Window Storage Tray Bolts
Hi Erv,
I waited to see if someone with a 69 would see your post but since no one has replied I'll take a stab.
And, I'm not sure if you're asking about the screws that mount the hinge to the rear bulkhead or the screws that connect the 2 parts of the hinge together.
The screws that mount the hinge to the rear bulkhead on my 71, #9421033, are a hex head with a captured flat washer, #10x24x5/8".
Hope that works for you.
Since the tray changed maybe the hinge and it's fasteners did too, I'm not sure.

IMG_Pivot Bolt.jpgI am looking for specs and possible source of the bolt identified as item#7. I belive the part number is 3958899. This is the tray pivot bolt.Comment

Hi Erv,
I can't help on that one.
Apparently when the tray changed the hinge or at least the pivot bolt changed too.
Sorry.

Re: 1969 (early) Rear Window Storage Tray Bolts
Erv, I am working on a one owner 70 and the bolt in question on this car is a 15/16 inch long recessed head with a "P" head mark. It also has a captive (loose fitting) flat washer.Comment

Erv,
In my experience I have seen two different bolts used here. 1 is the wiper door hinge bolt then second is the vacuum reservoir tank bolt. Both use the wiper door bolt bushing. Rich.Comment

Pivot Bolt.JPGHere is the original (?) bolt from the left side. I bought a window door hinge shoulder bolt but it did not work. Any thoughts of procuring a replace bolt?Comment

Re: 1969 (early) Rear Window Storage Tray Bolts
From what I have seen this bolt you picture is incorrect in that it is a sheet metal thread instead of a machine thread. (1/4- 20)Comment

Re: 1969 (early) Rear Window Storage Tray Bolts
That is not the correct bolt for your application. It should be a shouldered machine screw. There are two different shoulder lengths for the wiper system. The short one is for the actuator can and will work on the window tray pivot and the longer ones are for the wiper door. Corvette Central has them under 653125 (short), 653120 (long), & 653121 for the plastic bushing.

On a 70, and I don't know if there was a change between 69 and 70 or not, but the 70 does not use a J nut. The bracket on the bulk head has a square nut spot welded to it that the machine thread bolt screws into. Just like the square nuts that are spot welded to the lower splash pans and many other places. I have a friend who is restoring a 69. I will take a trip over there and look at his.Comment

Re: 1969 (early) Rear Window Storage Tray Bolts
Looking at your hinge it appears it is bolted on and not riveted. This would lead me to believe it has been touched at sometime.
Hing Bolt Org.jpg Here are some for sale on the ever credible Ebay, laugh out loud.
Does anyone have an unmolester early 69 they could check. These strings have been posted many times without a definitive conclusion. Would like to finalize this topic once and for all.
ThanksComment

Re: 1969 (early) Rear Window Storage Tray Bolts
Erv, if you look at the 69 AIM it shows the outer bracket screwed to the bulkhead with item 15, P/N9421033. I don't know why you are questioning the screws unless you believe production started with rivets and were later revised to screws. The pivot bolt is item 7, P/N3958899. What you are looking at though is the page and drawing of the last revision. Note this page starts with revision 18 dated 2-10-69 and ends with revision 23 dated 3-9-69. We do not know what the original 1969 MY drawing looked like and we don't know what revisions 1 thru 17 were. We can assume those revision were on or before 2-10-69. I believe my brackets to be original with the drivers side screwed to the bulkhead and the passenger side riveted to the bulkhead. I would like to hear from someone with a 68 AIM. Do the brackets show to be riveted or screwed to the bulkhead? As stated, I am of the belief that there was a change in early October 1968 from rivets to screws and the left side of the assembly line got the screws before the right side did. We have a number of people on this forum with early build dates. I know one car here was on the line 30 cars in front of mine. Mine has the outer bracket without the square weld nut threaded to accept a machine screw. When I got my car in 1981 there was a undersized bolt with two jam nuts on the end, which is obviously incorrect. That is why I can't give you a definitive answer to the correct pivot bolt. I can say that the inner bracket requires a bushing to be snug when using a wiper door actuator pivot bolt. There is no bushing depicted in the AIM drawing but remember, this is a 2-10-69 and later depiction. Perhaps the later bolt had a larger diameter shoulder that didn't require the bushing or maybe the correct bolt for the entire production year had a larger shoulder than the wiper door actuator bolt. I'm sure others will chime in with some more clues.
By the way, the AIM does not show the early coffee can wiper actuator and mounts so we are out of luck trying to compare part numbers. That change was revision 7 and dated 8-15-69 so the earlier parts numbers and depictions are not shown.Last edited by Michael B.; February 14, 2015, 11:28 AM.Comment

This is from a 69, with a build date C02. Very original 10,900 mile car.
