69 Wiper Access Door_Washer

[Wes G.]

According to the 69 AIMS (attached) there was a 'washer' (GM # 3940537) behind each bolt for the access door hinge. This 'washer' was removed and then re-added late in 68. I'm missing these on my 69 and was wondering if someone could provide me with some info regards to this washer: sizing, finish, where to purchase. I see in the Paragon catalogue they suggest using Loctite on the threads of the bolt which attaches this washer to prevent it from loosening up. Any comments? Thanks Wes 69 Wiper Access Door_Washer.jpg

Wes,
I believe those washers are light (some might say white) plastic material.

Yes, they are plastic. Several were dropped down into my inner fender while trying to install.

Re: 69 Wiper Access Door_Washer

Let me see if I can take my next guess: They are not flat washers, but rather shaped like a hat so that when installed form both sides there is no metal to metal contact.

I am working from memory when my 1969 closed the wiper door on the wipers as I was driving it home from the dealer. Body flexed as I crossed some RR tracks. A porter and I took it apart so I could have wipers to get home and bring the car back for proper repair another day. If I would have only known then what I know now I could have fixed it on the road.

When you order them, order a hundred so you'll have enough to finish the job after you drop the majority of them where the sun don't shine.

Agree with Reba and Mark. Start your job with more on hand than you think you'll need.

Re: 69 Wiper Access Door_Washer

I finally stuffed a towel in the fender opening and caught the last one or two on it.

Now that we have all told our war stories, me included, how about we tell Wes where to get them. I would, but the last ones I got came from Chevrolet, and I suspect that is an option that is no longer available to us.

Oh BTW: Locktite (the blue kind) might help make the bolt come out when you want it to in the future, but after about five years that bolt is in there for keeps unless you store your car in a temperature and humidity controlled environment. Trust me on that one.

I would try Richard Fortier. If he doesn 't have them, try Paragon, then ZIP.

Re: 69 Wiper Access Door_Washer

I use a piece of foam about 2 inches thick that conforms to the opening and is also then easy to remove.

Re: 69 Wiper Access Door_Washer

Thanks a bunch for all your timely tips and info! I learned about the 'black hole' when I dropped a screw down there. It took me almost a day to fish it out, that's with the motor removed. On the bright side I managed to retrieve a socket from one of the previous owners. Wes

I needed to remove the wiper access door on my 70. Two of those lettle bolts sheared off at the threaded portion of the bolt, leaving the threaded portion in the access door. I wanted to get a "new" door. I went to J&D Corvette and they had about 50 (I counted them) access doors in stock. Of the 50, I found ONE door that had no broken of bolts and no other damage. The access door are made of an aluminum pot metal material and the soft steel bolt will usually become corrosion welded into the door. Put Loctite on these little guys? Not me, I put anti-seize on them.

There are TWO parts involved here. The white plastic, "hat-shaped" pieces are the BUSHINGS. These were used for several locations on the wiper door mechanism and were GM #3922010. The part that Wes was referring to, GM #3940537, I believe is a thin spring washer.

Re: 69 Wiper Access Door_Washer

Howell I had one or two bolts break on my 1968. I removed the broken pieces of the bolts from door and installed heli-coils and original type bolts. This was done over 25 years ago. Have not had any problems with the repair.
