4426757 and 4426758 wedge

[Edward B.]

Can someone post a picture of the rear convertible "plates" that attach to the body opposite the ones that attach to the deck lid? (number 2 in the attachment below).

According to the picture on the DOC REBUILD PAGE, these were also used on the C2 convertibles, but somehow his picture just doesn't seem right. They appear to be too thick.

I have both of the brass plates (wedges) that attach to the deck lid itself, but I'm missing the two plastic (?) plates that attach to the body (P/N 4426757 for sure, and I think 4426758, but it doesn't show that in the AIM) so I'm looking for a couple.

Thanks
Ed

Attached are photos of the wedges.

1965-67 convertibles used these same wedges. However, they were not used at the same location on the car. They were used on the door jambs.

Thank you Joe. I guess Doc Rebuild has the right picture after all. But boy, they just look too thick to work on the deck lid! There's not a lot of room between the brass wedges on the deck lid and the body. I'll have to get a set and see what happens.

Before your reply I was thinking THESE on ebay would be correct, since they appear more like the drawing in the AIM, but I wasn't sure about metal on metal contact. That seller also has the same thing in plastic, but since it's not what I need, I'll go with THESE if they're "correct". (and going by your picture, they are)

The metal wedges would not be right, at all. The plastic ones might work OK but I don't think they are the same as the 4426757 and 4426758.

No, the plastic ones are exactly the same as the metal ones, but plastic. They're much thinner than the 4426757 and 758.

I'll get the ones you have, which I'm assuming are plastic, right?

Thanks again

Yes, mine are definitely plastic.

A followup question...

The 68 and 69 AIM both show only one part number for the two rear deck lid "plates", P/N 4426757. I can't believe only one part was used on both sides though since Chevrolet typically had mirror images of the parts for left and right. The AIM states "Plate R.H. & L.H.", and usually there would be two part numbers listed. In this case, going by the normal AIM part numbering format, it would be "4426757-8".

Since only 4426757 is listed, does this mean there's a mistake in the AIM (missing the "-8") or did they really only use one part (the driver side) for both sides?

If anyone out there has these plates (wedges) on their 68 or 69 (and early 70 I believe), can you check both sides of your car and see if both wedges are the same, or mirror images of themselves?

As a side note, the 68 AIM has Note 4 which states "Was 4444736 plate", which in the P&A had a mirror image for the other side (P/N 4444737). But even in the 68 AIM, the -7 isn't listed so I'm not sure what's going on.

I KNOW the C2 door wedges are mirror images, because the exact same two parts were used on the first generation Camaro convertible (see mine attached), so either the rear deck just used ONE part, or the AIM is missing the "-8" part number.

Thanks

The same plastic plate, GM #4426757, was used for both sides. The pictures I posted above both show the left side plate. Note the rounded end pointing forward. On the right side the rounded end points rearward. Thus, the same plate was used for both sides.

That's interesting Joe. I contacted the seller of THIS CAR on ebay and he said they were mirror images of each other! I wonder if they were "supposed" to use both the 4426757 and 4426758 at the factory, but made mistakes and only installed one on some of the cars? Remember my shock mount? One is the F41 and the other is the standard!! Could it be another issue like this?

Given the fact that the AIM only specifies one part number and that's exactly how my car was built, I would say that's how GM intended the cars to be built.

Re: 4426757 and 4426758 wedge

I tend to agree. Especially after looking at the P&A (see attached). No mention of the 758 in group 12.170, but then again, while it lists the 757 wedge, it only shows 1 being used!

Typical!!
