56-62 Windshield Posts - what years had Visors

[Ronald L.]

Looking for help to clarify the Subject line question as via the web, there seem to be any and every year option claimed.

So the question is - what did the side posts look like with no sun visor and which years?

And Which years got visors and what did the post look like?

Re: 56-62 Windshield Posts - what years had Visors

My 61 had visors and I think they became standard in 61 (along with windshield washers), optional for a few years before that..
The problem with retro-fitting them on earlier cars is attaching them to the chrome header bar from what I understand.

Perhaps I've been misled, but my understanding about the differences in posts is how the weatherstrip attaches, without regard to whether or not the center bar has provisions for weatherstrips

Re: 56-62 Windshield Posts - what years had Visors

Anyone have pictures of what with sun visors and no sun visors looks like?

Re: 56-62 Windshield Posts - what years had Visors

These are all I have from my 61 windshield replacement, IIRC one post was from a '62 but both years had visors.
Its all I have.

Ron, I did a bit more research after our PM's....

RPO 261 Sunshades first appeared in 1959, and carried through 1960. Not available 1956 to 1958. 1961, 1962 Sunshades were standard.

1956 - 1958 Posts 3716385 L ,3716386 R

1959 - 1960 Posts 3762553 L, 3762554 R - without RPO261 Sunshades

1959 - 1960 Posts 3762679 L, 3762680 R - with RPO261 Sunshades
These had a threaded hole for the sunshade outer mount rod machine screw in the upper inner depression, covered by the full width rounded stainless header trim. Note that the trim had holes for the outer mount rod screws to thread into the posts, along with a welded nutplate in the center of the trim for the inner sunshade mount rod machine screws. Cars without sunshades used a trim without the sunshade 2 mount rod holes or center nutplate for 2 inner screws. Both trims had 4 holes to mount to the windshield top frame using sheet metal screws.

I believe the same post casting numbers(without RPO 261) were used for RPO 261 posts, but now it had drilled and threaded holes for the sunshade screws so it carried the new part numbers. Therefore the posts would be identical except for the drilled and tapped holes. According to my quick 1962 P&A Catalog research, in service you could not buy a non-sunshade post, only the sunshade drilled and tapped version. I'm not sure about the 1959-1961 P&A info though, but I would think it made sense to keep inventory efficient.

1961 - 1962 Posts 3762679 L, 3762680 R - with standard equipment Sunshades (note same part# as 1959 -1960 with RPO 261)

Here is a 1959 pair from a original March built car. It had RPO 261 sunshades. In the lower left you can barely see a hole for the screw.

Here is a 1961 post(standard sunshade car), but to show the screw hole and trim hole. Note this trim was enlarged by a previous assailant.

Here is the header trim used with sunshades. Note nutplate at center area.

It should be noted is very difficult to add sunshades to a non-sunshade car unless you have this special trim. It's easy to drill and tap the posts, but keeping the sunshade mount rods tight in a trim not designed for it is nearly impossible.

Also found this CC link with some info.....

Here is some pertinent info and photos from there for reference if their link disappears....
"There are two variations of windshield frame posts. The 1956-58 version has a square notch relief for the door post with the upper window stop (Corvette Central part number 281009). The 1959-62 version has an angled notch to allow for the later style door weatherstrip, which features a built-in stop and continues over the door post (Corvette Central part number 631010)."

Rich,
Wonderful - thank you so much for the details - this should be a Sticky as the difinitive guide to sort out these posts.

Re: 56-62 Windshield Posts - what years had Visors

Rich, I'm still not clear which hole is the sunshade, I think I see the differences in the notch, and if sun shade was not available untiol 1959, then a notched post should not have the sun shade screw hole...
Can you post a picture or someon that can show that please?

Ron, Those CC pictures show the windshield posts then the door posts below them. A little misleading I guess.

Here is the previous(edited) photo pointing out the hole.(I showed the wrong post and hole earlier so I fixed that in the previous post.)

They're covered by the header trim but seen through the screw hole in the trim itself. Here are some without the trim installed.

Correct a earlier square notched post should NOT have the screw hole if original. I don't have any photos showing that but if it's a 56-58 (3716385 L ,3716386 R) post, the area where the hole is on the later posts would simply be undrilled.

The caveat is it's possible that a prior 56-58 owner had sunshades installed and had to drill and tap the posts, then acquired the correct header trim with the nutplates. Of course the entire windshield would have had to come apart to remove the old header trim.... properly without damage and drilling the posts with glass installed is a recipe for disaster.

Re: 56-62 Windshield Posts - what years had Visors

Adding more information and notes for future reference.

- I added notes to the CC photos to add detail to their basic description.

- Upon closer examination they appear to have made a few errors. They overlooked "62"(59-61), in their Door Post picture and they link referenced the wrong part# for the 59-62 door weatherstrip. Their link is to the 56-58 part#.

- I captured all of their pertinent parts photos and added notes.

- I added notes to their Windshield Post picture showing the notch details and sunshade hole(or no hole) areas.

Rich,
Thanks so much for providing clarification.


Very comprehensive I can see finally the differences.
