Especially in the rarified 63 world, LICS often has superior parts and I'll pay a premium to get them if I have to....

As this thread illustrates profusely, NOTHING is worse than a part that doesn't fit or function correctly and requires a complete "do over"...
I've run into this on fuel tank sending units, glove box light switches, tail light sockets, repro dash gauges and on and on..

So the one on the right is manufactured by corvette rubber company?

@renostalliion I'm not sure. I would need to call them. I trust Long Island, so I didn't need to ask. I've only had to return one item to them over the years.

There are not that many companies that make weatherstrip. Part of the issue is that there are a lot of small companies that got greedy. I don't mean that by they shouldn't do this but they all paid the same guy that was making weatherstrip for all of them. I mean how many door weatherstrips do we need. CRC is the best quality out there but it's also not 100% right on some of the year cars. Some of the original weatherstrip is no longer legal to make in the U.S. which is why it was made in India, but that is also where the issues started and formulas started to change etc in it. We sell CRC and right or wrong on certain application, I would stick with them no matter what. I also don't have any fit issues with theirs, I would say 99% of the any issue I have had with a CRC part has been a customer issue and not a part issue.

I agree with DansYellow66. I used the technique of marking the striker location and then moving the striker out until door closed and then given some time started moving striker back to it's original position. This was all done during the hot summer months here in central Kentucky on my '74 Coupe which has since been sold. I'm now using the same technique on my '67 Coupe. We don't have the hot weather to help right now but that's my plan. On an earlier post showing the difference between Corvette Central & Long Island, the profile of the Corvette Central looks very much like the original GM weatherstrip profile.

Just curious ... anyone know how GM originally did the weatherstrip on these cars?

unsure of the vettes but many 60s and older cars' door frames were tweaked by literally bending it out up top.

I'm sure GM spec'd very pliable weather strip of fairly thin rubber section in the cell walls so it would seal but not make the doors hard to close. They had to assemble them once and have them work without making adjustments over time. Also need to be sure and v-cut the ends where they meet under the doors so the cells are vented to allow air to escape as the door compresses the WS on closing. I think there is a detail in the AIM. If the ends are butt glued together there's no easy place for the air to vent out.

Purchased my WS from Zip, installed last Summer after car was painted.
The rubber was very pliable, and apparently is manufactured by Corvette Rubber.
Doors had been fitted loosely after painting.

After installation (did one foot at a time), I slammed the doors shut,left them closed for 24 hours.
Minor adjustments were necessary, but the WS kit worked nicely.

How long are you letting the seals take a set before starting on the fit?

Its a two year old thread, I'm sure the weatherstrip has taken a "set" by now
