Door glass seals
 

Hey everybody,

I tried to do some searching on this and found some old posts, so I wondered about reviving this discussion. I bought some custom window seal kits for my 72 C20 from LMC.

These don't seem to fit at all. I called LMC and they told me the pieces were 27" long, which wouldn't fit without being trimmed. Even when trimmed they don't fit properly along side the triangle vent window. Has anyone got any suggestions and advice on another brand or a way to make these fit and look good. I've got some photos below of my attempts. Thanks!

I feel your pain , they are a P.I.T.A ! I dont have the outer on my drivers door because after the second attempt (destroying the Part) I gave up .

Lmc seal suck. There felt kit worked good. But my door seals hardly touch glass to seal

This is what I always used but it looks like they are discontinued. Maybe Classic industries just don't handle them any more.

They were made in the USA by Clark Industries they were the nicest ones I could find at the time.....

I know that Repops made the weatherstrips for Precision at one time but Now I'm not sure.

By their web site it looks like they still make the window kits.

I would check with GMCPauls and see what they say.

The ones from GMCPauls requires trimming. I am a week or so away from installing them.
Sorry, I don't recall if they were in a labeled wrapper or not and can't recall brand.

I bought LMC first and they are crap. Bought Steele rubber. Also crap. Bought precision and they are a great fit. No trimming. Just make sure the slots inside the door are flat and not bulged out. If not flat it won't fit properly. Also as someone on the forum stated on the 72 there is a screw on the door under the wing window. You need to slightly loosen the screw to slide in the outer piece. No matter what you do they are still a real booger to install. You'll be shaking by the time you're through. The screw I mentioned is in your first photo. It's in the indentation on the door below the wing.

Howzzzit, I'm guessing this is the Precision set you were referring to? I'll have to grab a set of these and get to work.

They will have with chrome bead and without. I used the chrome bead version. Hopefully the quality is still good. Go to their website and they have a video of installation. Don't forget to loosen the magic screw when replacing.

Re: Door glass seals
 

I've got a set on order. Should be here tomorrow seeing as they are 3 hours away from me over in Wisconsin. Perhaps I'll get them in this weekend. I'll post pictures as I go and keep ya updated. Thanks again the for advice. Appreciate it.

Re: Door glass seals
 

I recommend reading my experience with it and the guidance I received from the folks here on the forum. And the pictures. The felts fit on the inside of the glass channel, and you need to shave and smash them in order to fit. Smash it in a vise. The squeegee may need to be trimmed just a little. https://67-72chevytrucks.com/vboard/...d.php?t=738367

Re: Door glass seals
 

Watch the install video on precision. Remember to have the slots in the door flat or it will end up with a gap between molding and door. These are pretty much a one shot deal. You'll probably booger them trying to remove. My slots were easy to flatten with a broad tip screwdriver. Just protect the window. I also had the door panels off and removed the window stop inside the door. You can then lower the window a little more and give yourself a little more wiggle room. Anyway it's still no fun. You can do it. Also, use tape on your door paint.

Update - - Got the window seals from Precision out of WI and they feel like they are waaaay better quality than LMC, so thank you Howzzzit for a heads up on that one. I'll try and get them installed tonight and we'll see how it goes.

Man, I love this forum board. This place is so much better than any YouTube channel for info. We need to arrange a get together with all of our community assisted repaired trucks.

I got the door glass seals in last night and they are a lot better than LMC's seals. These were super easy to install and are high quality. I paid $84.00 for these before shipping and have learned as I've gotten older, you get what you pay for. I loosened the screw in the window vent and that helped to get the seal seated. The video on Precision's website was really helpful as well.

Here's their website again if anyone needs it.

I will definitely be buying more parts from them.

Below are the installed photos. A little wavy, but definitely better than what I had. Thanks to everyone for the input.

Re: Door glass seals
 

We've offered Precision seals for 25 + years now. Top notch company that stands behind what they manufacturer.

I used Precision for all glass and doors. Short the vent rubber anyway, I didn't rebuild them. Everything went smoothly.

Re: Door glass seals
 

working on this too. can anyone tell me what the width of the window slot should be prior to installing the seal and felt?

Re: Door glass seals
 

Precision Seals all the way.
I got mine from Wes Hepp @ https://www.classicheartbeat.com/

A little trimming required.

Re: Door glass seals
 

Those look spectacular.

The ones with the bright stainless bead were not ever factory installed on trucks, right? My '72 Cheyenne Super, and '70 Blazer CST just had the normal black.

Re: Door glass seals
 

Unsure about them originally from the factory.:confused:
Very pleased that this stainless option was available from Precision.
My Windshield, Rear window and Door to Cab seals are also from them.
Other reproduction part manufacturers could learn a lesson from Precision about aftermarket restoration parts for quality and fitment.

Re: Door glass seals
 

They were factory on my 72 Cheyenne C10. I replaced with same from Precision. A little extra bling.

Re: Door glass seals
 

Did did my truck a few weeks ago and used Precision products. Very happy with the results and not that hard to install.

Re: Door glass seals
 

The width of the slots on my Burban's windows vary.
Driver's side front 1-1/8"
Driver's side rear 1"
Passenger side front 1"
Passenger side rear 1-1/16"
