Default 63 Split window ridge offset

I was looking at a 63 split window recently and I noticed that the raised ridge on the top was not centered between the rear windows. I understand that with the rear windows being curved that they are pretty much limited to how they can set into the body.

This coupe was supposed to be early production since it had the "tool trays" under the font seats. Now is the ridge being off center on this coupe something that was not uncommon on early production 63's?

I am sure that there are people on this site that would know the answer so let me thank you in advance.

Are you are talking about the ridge that runs from the front to the back of the car? If so, it is in the center of the windshield and in the center of the rear windows to the center of the rear tail light panel. If not some one did some poor body work.

AFAIK the ridge was not "placed" by workers (which would allow for variance from car to ca)r, but pulled from a mold with the whole top, or at least the rear section. So all SWCs would have identically centered split ridges. Sounds to me like an imperfect "repair" done at some point after the car was sold.

Correct - the "ridge" was a feature in the mold, and didn't move.

Maybe the car is a '64 - '67 with a really bad reverse-engineered job to a '63.

65 Pro Vette probably nailed it - poor body work. That ridge is gradual enough that careless sanding on one side can actually shift the crest of the ridge to the side. Same with the belt line and all other character lines on fiberglass. When I prepped my car for paint I would guide coat the ridge, belt line, tops ridge of fenders, etc and sand one side up to the edge. The guide coat remaining on the other side of the peak presented a clear contract by which the straightness or curve of the peak could be judged for conformity and uniformity. Then work the other side up to the line until there was a almost paper thin line of guide coat left that should look perfectly contoured - or I got to do it all over again. It sort of amazed me how easily you could adjust the contour and sharpen them up with careful cross hatch sanding at 45 degrees towards the peak. I suspect someone sort of ham-fisted did some body work on that car.

DansYellow66, I think you nailed it. The fiberglass back then was not the best and if someone sprayed heavy coats of Fiberfill or something like it and didn't pay attention to what they were doing in the sanding, being off center could happen real easily.

I forgot to mention that back in the late 80's the car did have a body off restoration so what you said could make sense.

Thanks for the replies.

A little offset in the split? No worries - you should see some of the Frankenmobiles being sold as restored SWCs...

Years ago we had a 63 in our shop that had the split bar removed and had a 64-67 rear glass in the car. Possibly someone removed the bar at some point in time and then replaced it? Just a hunch..
