1968 door panel window wipes, 5th Judging Guide

[Dale C.]

I just noticed the new 5th edition Judging guide on page 23 states that the 1968 door panel window wipes were rubber on the outside. That may have been true at some time during production but two of the three production types were the #3937267-8 seal and 3945289-90 seal which appear to have been the whiskered felt type. The GM part number 3937267 was a whiskered wipe. This part number is depicted in the 68 AIM 1 K 3 in the chance of 1-18-68 and was actually the felt type found in numerous NOS examples. The felt type is also referenced in Dobbins Fact Book on page 50. His example was a whiskered 13818 which was built very close to my whiskered 13417. There is also a reference to, (in an origional AIM) a "L" shaped rubber seal as a part number 3937923. There would almost have to be two separate part numbers for a rubber seal and a felt seal. I have pretty firm evidence for this distinction. Interesting stuff - the 68!

My 68 #15742 has original rubber outer window seals.

My 68 #15742 has original rubber outer window seals.

My July 68 built original coupe is the same.

My late June build (6/26) 33k coupe are rubber also.

Re: 1968 door panel window wipes, 5th Judging Guide

All the '68's I have looked at had the rubber type.

I think that the 1-18-68 (6) change to t

he 3937267-8 seal was in fact to a whiskered wipe which makes the JM claim too narrow in scope, declaring all of 68 being the rubber type. Dobbins example, my car, others on this site, and many NOS samples of 3937267-8 being felt mean we should not be the final authority here. Joe Lucia was not so emphatic to make claim as to how the wipe evolved during the 68 production. He said he didn't know the answer. I also have some interesting correspondence from the GM Hq. copy of the aim that address yet another part number on a requisition request that addresses a drawing 3961497 dated 8-68 that lists all the weather stripping and has the wipe listed as 3937924. There are now four part numbers for that wipe?????? Point being, I don't think we are at a point so as in invalidate some of the whiskered outer felt type cars. By the way I was the guy at Frisco that pointed out the different vacuum pickup for the 68 BB with A/C, ie. it's not ported off carb.

Dale:
Bear with me, I am just trying to follow along here. I am just a simple, sometimes dense old man living in the cold country.... 4-degrees on my long walk to the shop this morning. I am not trying to argue with you. If something is wrong in the TIM&JG, we need to address it. Like so many other things, before "WE" change it, I need to understand why and what we are changing, so I can explain it (put it in writing) in the manual. My theory... If it's worth explaining, it's also worth having a picture. With that being said...

Yesterday you specifically addressed the rubber window wipers. Do you agree or disagree all 68's had the rubber window wipers above the "wiskers" ???

I think.. your next post addresses the wiskers, or as the AIM refers to them, the Seal Assy. I agree there are at least three model year 68 Seal Assy's (wiskers). I do not know what the difference is between those. Are they all the fuzzy wisker type? Is it just the mounting? Do you know? Before we ask a judge to judge it, we need to tell the judges what should be there.

3961497 dated 8-68 is probably a 69 model year part, and I think it's convertible (19467) part? The AIM list 3966641-2 (19437). But, I cannot find 3961497 in the 1953-1970 Corvette Parts Catalog dated April 1970 or the 1968 or 1969 AIM.

So, if you were to change the 68-69 TIM&JG, how would you word it. Also, can you provide pictures to help explain the differences?

Right now, I am up to 91 unique items on a 1968. In the next update, I would like to address each of these, but I am not smart enough to "know it all". I need help from other people, that do know some of the differences.

Maybe the owner of the complete '68 AIM could shed some light, at least to the referenced running changes shown in the manual

Re: 1968 door panel window wipes, 5th Judging Guide

Thanks Richard
That supports what I'm trying to convince the NCRS JM authors of. There is a lot of evidence out there that the outer wipes could possibly be whiskers and not exclusively the rubber type.

You have already heard from someone who has the complete (such as it is) 1968 AIM.

[Dale C.]

Re: 1968 door panel window wipes, 5th Judging Guide

I'm not positive about anything on the 68 either and far from as knowledgeable as the NCRS. I'm just submitting some data I've come across that may open up some other possibilities. I posted some limited material I found that talks about the weather stripping issue. Boy a complete AIM as a reference would be nice.
Dale

I have an origional AIM but I don't think it is complete enough to draw a definitive conclusion from. It came from a GM Hq. reference library and has a few notes about various issues. One happened to be some hand written and printed text about weather stripping. Maybe someone could use the info. to help clarify why there is confusion now. It does appear that there was some in the past, as Joe Lucia was left scratching his head in an earlier post.

Re: 1968 door panel window wipes, 5th Judging Guide

You know Gary as I look at it that hand written note speaks of a L shape rubber strip between the felt. ????

Re: 1968 door panel window wipes, 5th Judging Guide

Attached is a picture of the inner seal and wisker I bought. The rubber flap is stapled together, sandwiched together. I think the outer was the same way, for awhile.
