[Edward J.]

I am going to be starting the reinstall of some of my interior pieces.and was wondering if any one has some pic.s of the correct screw heads and there locations for radio side panels, and kick panels and the rear fiberglass panels behind seats, when removing my interor pieces there were no two screws correctly located. I need some help, I believe I have just about all the correct screws.( car is a convertible) Thanks for your help Ed.

Ed,

This ought to be fun

I might be able to help with a few of these, but some were specific to 1963.


Radio Panel Screws (Section 1-B7, Item 11):
The first one is easy, the same radio side panel screws (GM # 3777486) were used from 1963-1967. For 1967 there are three on the driver’s side, two on the passenger side, not sure if that’s the same for 1963 or not (how many holes in the two radio side cover panels?). The chrome screw should be a #10-12 x 5/8” with a pointed tip, Philips washer-head (1/2” diameter). One piece, no attached washer. Most originals that I've seen have a faint diamond or triangle pattern on the underside of the head.


Kick Panel Screws (Section 1-B9, items 8 & 9):
One of the two kick panel screws used in 1963 (Section 1-B9, items 8 & 9) was also used through 1967. Yours is called out as Item 8, GM 4751359 Screw, it looks like you need four per side. These chrome screws are Philips head, with a “washer-face” or “washer head” similar to the radio side panel screws, but they are longer (#8-18 x 1”) and DO have an attached washer (1/2” diameter).

From the ’63 AIM it looks like you need three of Item 9 Screw per side. My 63 AIM shows part number 3826362 crossed out and replaced with 162406, but there is no confirmation in the Revision Record. Someone with a ’63 will have to help on that one.


Rear Quarter Trim Panels, Convertible (Section 1-B28):
It looks like you need Item 8 at the bottom (GM 9418741 Screw) and Item 13 at the top (GM 3777486 Screw). The top screw is the same as your radio panel screw, referenced above. The bottom screw for the rear quarter trim panel is a screw not used in 1967, so I don’t have one to describe. I checked my parts books and didn’t find 9418741 listed, so someone with a ’63 will have to chime in.

There may also be an additional tiny chrome trim screw at the bottom of the panel, I have seen that on later cars but I don’t know if it was used in 1963.

Hopefully someone has pictures, if not, I can take some pictures of the ones that I have and post them.

Ed, I'll look for my original radio side panel screws and post a picture later.

On the radio side panel, the number of screws per side changed during production. Initially there were 3 screws per side. One forward and two aft.

My contention is, that around the time of AM/FM becoming the standard radio (VIN 11750 + or - a few), the number of screws per side changed from three to two. One forward and one in upper aft area.

On the quarter trim. Best I recall the carpet was not screwed to the trim. It may have been glued but I'm not sure.

Harry,My radio trim plates have 2 screws aft.and maybe one forward my car is a AM ONLY.


Scott thanks for taking the time to describe the screws, since I have most of the original screws. it helps with the assy.

Re: 63 interior screws- help

Guys thanks for you help, I Will need to find a few radio side panel screws, I noted the Corvette Central sells the screws and appear correct, I wonder if you won't mind looking at them and give me you opinion?

Re: 63 interior screws- help

Can someone with a early 63 check to see if the 3777486 radio screw is also used in the front of the radio trim panel. I am having some problem trying to start this size screw (seems to large in diameter), there is no J nut it just threads into the heater Y on both sides. I am wondering if a different screw is used on the heater duct.

Also, Are these screws interior color or just chrome.

Thanks,

Ed,

The radio side panel screws at CC look fairly close, hard to tell for sure without a direct view. They look shorter than originals. I count four threads on the CC example, and six on the originals. Doesn't sound like much, but two full threads with that spacing (#10-12 thread) works out to be about 3/16" shorter than originals.

Also, an update to my earlier post, it looks like I was wrong about the number of radio side panel screws required. I have three holes in the driver side panel and two in the passenger side panel, but if I understand correctly, the upper middle hole on the driver's side takes a regular philips head screw inserted from the back side, securing the turn signal flasher bracket on the outside.

Wayne Midkiff posted a picture of the back side screw securing the flasher bracket in this Thread regarding a 1966 Corvette: https://www.forums.ncrs.org/showthre...+clip&uid=3999 . The 1966 and 1967 AIMs show the same Screw (GM 9419328) and flasher Clip (GM 3866440) being used for both model years, on UPC 12-B1.

Here is a picture of the front side that John Hinckley posted in another Thread, see post #4: https://www.forums.ncrs.org/showthre...+clip&uid=8133

My turn signal bracket was missing, the flasher was taped up under the dash, and so I assumed the third hole on the radio side panel took a chrome screw like the other two on the LH panel. The 1967 AIM page for the radio side panels (1ASM-E2) implies that the same screw is used in all three holes, but the 1966 AIM does not. The '66 AIM shows only the front and rear holes, ignoring the middle hole until page 12-B1. I don't know why the 67 AIM tries to put two different screws into the upper middle radio side panel hole.

If I am still in error, someone please explain

Tim, Thats a good question as when corvette central sells those repro screws they come in a set of 4. I wonder if there is another type of screw there.

Hi Scott thanks for your input on those screws. As for 63 the flasher is located in the fuse panel, The later years it was moved to the rear of the side panel.
