65 wiper blades holders

[Keith B.]

At a recent reginal meet my dad was explained to him that he has passenger car wiper blade holders on his car. Now the holders and rubber inserts matched the description of the current judging manual. it was explained to him the correct Corvette holders will deflect when pushed to lay flat while passenger cars will still have a slight curve. Is this correct?

Re: 65 wiper blades holders

It is correct in saying that passenger car wiper blade holders have more of a curve to them than Corvette wiper blade holders.

Re: 65 wiper blades holders

So the Corvette blades will be flat with or without pressure applied to them

Re: 65 wiper blades holders

Mike,

With the wipers resisting on the windshield glass, is the difference in curvature readily apparent? Or does it require lifting the holder from the glass to detect the incorrect curvature?

FWIW> Here is a picture of "Trico Arms/Inserts" on my Very Very Early (Sept. 65) 66 Corvette.
Note the arms are flat and not shiny. IIRC the Judging Guide(#6) indicates the arms can come
other way(shiny vs. non-shiny) on early 66's. I believe these arms are the same for the 65's
except for the fact the 65's are shiny. Larry P.S. As you can see they lay very flat on the Windshield.

Gary,
it is readily apparent without lifting the blade.

Brian,

Thanks for that clarification. Fair game for assessing the curvature then..

Re: 65 wiper blades holders

Hi Brian. What is your opinion of the ones in Larry's photo. To me the forward half looks to "bow" even when pressured against the windshield.

Re: 65 wiper blades holders

Larry, the discussion is not about the finish on the blade holders (although there is always lots of discussion about this). The question is the curve of the forward half of the wiper blade holder. The discussion now circulating is about the shape of this forward half and whether it is different between Corvettes of the era and passenger cars. As I understand it the Corvette wipers sit much flatter in this section than the passenger car wiper holders. I would really like to see a side by side comparison if anyone can provide definitive proof. Thanks.

Re: 65 wiper blades holders

If you set a passenger car wiper blade holder and a Corvette wiper blade holder down side by side you can see the difference in curvature. The passenger car curvature is much more pronounced than the Corvette.

Re: 65 wiper blades holders

So does the GM parts manual show two different part numbers for these holders?

Re: 65 wiper blades holders

I thought I read somewhere that the Corvette arms/holdersWhere different in size (not as long) as other GM cars. They are
Unique to Corvettes AFAIK.Larry
Update on some research.
There was also a Trico blade assembly available in SERVICE for 1965-67 Corvettes, although I have no information that it was used in PRODUCTION. This was GM #3899508.(Per J/L) This assembly is 14-7/8" long. Normal length for 65-67's was 15".
So if one had the shorter version would this not make the "bend"more pronounced?? Larry

Re: 65 wiper blades holders

Can someone provide a photo of the two different wipers blade holders please. I would assume that there are many more "passenger" car wiper blade holders in the market out there than there are original Corvette wiper blade holders and I for one would like to be able to distinguish between the two when I see them on cars or for sale. What model years does this difference apply to?

my parts book states 63-65 is 3941969 for 14 7/8 trico and 377974 for 15 5/32 anco. I need to look thought my Chevelle parts book to find that data. will this info be addressed in the judging manual?

Keith;Since there is such a small difference and so hard to tell I DOUBT that there will be any change in the TM & JM. JMHO>Larry
