Windshield gaskets

-
Ok fellas curiosity struck! I bought a windsheild gasket from soff seal for my dart sport. It is correct since it has the application on the bag for the body style. Question is how good/ correct fit will it be? Haven't found any reviews or comments that state fitment of this brand. Used to be hailed as good years ago but just unsure.:eek:
You are the man. Let us know. Heat will be your friend. Lay it out in it's intended configuration and heat it up.
 
Found one here with a label, should work right? Lol.:poke:
Seriously, Soff seal is a good product from what I know and so is Steele.
Problem some people dont understand is Mopars stupidity with a one year design on windshield gasket and mylar lockstrip for 67. Precision is the only one to lay their pecker on the table and pony up for tooling. As said above, I wouldnt be surprised if Precision stop making the mylar.

I'm not sure why this so difficult to believe.
The Brite-lock strips for 1967 are rigid and nothing like the strips used in the '70s on the Rams as well as by other manufacturers (such as Audi). Those later lockstrips are narrower and flexible.
These do not bend easily even with heat. When I bough the repops, only straight sections were available. To replace the pieces for the notchback rear windows required gentle heating and lots of patience. I still broke one. Fortunately I was able to find an NOS piece at a swap meet.

In cross section, they look like this.

The first company to sell repops was Mitchels and then Year One carried them. Since both are retailers, don't know who was making them. At that time, new gaskets were not available. I still have the originals in mine. We used a 3M weathertrip sealer where it seals to the metal flange.

As the lockstrips lengthwise shrink over time, the gaps need to be filled with little cutoffs of lockstrip or a leak can develop in those corners.

It was a neat system which would have been OK if the plastic had longer term stability. :(
 
In regards to the quality of the Soff Seal windshield gasket, I would suspect that the gasket is actually a Precision piece that has been placed into a Soff Seal package. I may be wrong, but most manufactures buy from one another so as to have product coverage. Steele does not have that large of a vendor network as they pretty much market their own product line and does a very good job with it.

I know that it is an inherent problem with the traditional mylar seals to shrink. Does anyone have any knowledge on how the Precision mylar piece stands up? I would think that since these cars mostly are kept indoors and out of the elements except for when the owner takes it out for a pleasure drive that they would hold up for many years.

For the person who thought that the Precision mylar seal could be rolled up for shipping purposes, Precision ships the mylar inserts to us in very long boxes which have to go oversize due to the length of the product. That is one reason for the cost on these pieces being what it is.

This will give you some idea, assuming Mitchell's lockstrips were the same thing.
Purchased the lockstrips late March 1993 and installed that summer. Exception- one rear window strip which was installed after the Englishtown Swap meet - probably June.

Both of the photos below are Summer 2016.
The car is normally garage kept, but I've never worked at a place where it could be parked inside. So it has seen more weather than a show car, but less than a typical commuter car.
