Even with the glass on a bench and the gasket in place it's obvious that trim isn't going to sit nice let alone when you try the install. It just pops out.

**Classic Heartbeat** · 11-29-2011, 10:57 PM

Both. Repro trim can give us trouble, but we get it done. We have found problems with inconstancies in the dementions of the glass. I suspect that some of the problems experienced may have that problem. WES

A few months ago I had to redo the top on my truck.I wound up ordering a few parts from LMC,needless to say windeheild strip was one of them,mine bunched just like that,That was using the original trim also.
I called LMC back told them the problem and they sent another one no charge and they girl said they would have R&D to look into it.they tried to make out that i was the only one having this problem.2 reinstalls later and still the same if not worst problem yet.I've talked to WES and needless to say i won't never order from LMC anymore.Rubber wasn't wasn't to only problem i've had with their parts.It took 3 trys for a good power steering boxes to get one good one.
I've talked to WES a couple of times about my problems and he explained a few things to me. Get LMC to do that.yea right.I know where my parts will come from now. yae wes ,i'm about 2400 miles from you but you will talk to your customers.thanks jason

I was under the impression that leaks were expected by GM. They designed drain holes in the corners of the dash where it meets the bottom edge of the windshield.

**special-K** · 03-17-2012, 10:29 AM

GM used a white sealant on the bottom and up the sides 6-8" and black butyl at the top outside on the flange. That's why original windshields didn't leak. The drain holes are for water that gets in the cowl area.

RobbySuburban · 03-30-2012, 12:09 PM

I had mine replaced last summer with a Precision seal with no problems. Most installs nowadays are urethane glue ins so it's important to get an experience tech who knows how to do these older style jobs.

**DeadheadNM** · 08-21-2012, 06:05 PM

VICTORY!!!!!!

With OEM 71-72 windshield trim and a new matching Precision gasket the install was completed IN UNDER ONE HOUR with no difficulty.

My recommendation: Use OEM windshield trim and DO NOT waste $$$ on repro trim.

litew8 · 08-21-2012, 06:30 PM

What do you mean by this? "new matching Precision gasket"

Means we cut the existing Precision gasket to spare possible windshield damage and replaced that gasket with a new Precision gasket correct for 71-72 trim. There are two possible gaskets for use with windshield trim: one for the shallow 71-72 trim style and a second for the deep 70 and earlier trim style.

litew8 · 08-21-2012, 10:20 PM

Okay, still at a loss - why do you mention OEM? Precision isn't the OEM.

No prob - The trim I used this time is OEM (used General Motors) but the gasket is new from Precision correct for the trim style (year), which in this case was 71-72 (rather than the 70 and earlier).

Reproduction trim is, in my experience, a total waste of money so go with good used OEM windshield trim when you can but be sure to get the gasket that fits whatever year trim you use.

ortegamotor · 08-21-2012, 08:11 PM

yeah i replaced my on a 69 with a 72 shield, and trim. but the gasket was for a earlier truck. the trim would not stay in. then i figured out the i was using the wrong trim so i pulled an earlier trim set up out of storage and installed it on the wind , then installed the window with the help of my friend a rope cord , and some soapy water. we had it installed in 10 min. My advice just go with the earlier style trim it has a bigger lip on it so it seems to stay in the gasket better then the 71-72.

Good luck.

**michael bustamante** · 08-21-2012, 08:37 PM

deadhead, i was just going to tell you i have 67-70 trim sittin in my garage if you needed it but you got it installed.....good for you!!!

Thanks Mike! If you need similar work go see Sean at Lomas Auto Glass..he went the extra mile for me where other glass guys flaked. Pete

Thanks d, more pics just added.

**DeadheadNM** · 08-24-2012, 12:12 PM

On a different but related note: I'd like to advocate for better vent window seals. The aftermarket vent seals I installed (unsure of brand) began to crack in less than 6 months. It's a lot of work to redo the vent windows just to have the rubber breakdown that fast. The factory seals get stiff but don't seem to crack. If Precision can manufacture vent seals from a rubber compound similar to the windshield gasket maybe that would solve the problem and win a lot of customers. Thanks, Pete

RexDodge · 08-24-2012, 12:31 PM

Just read through this thread. I keep reading about using "rope cord". I have done several and never broken one (knock on wood). I use para cord and lots of dish soap. The para cord is very very strong and as thin as a cheap shoe lace...works great! *Sorry if this was already posted...

JumboAMONGus · 08-24-2012, 05:07 PM

i got a window seal and had it professionally installed to and it leaks three times and still bunches up in corner its like they made the rubber to long ,my old one i took out was the same way leaks bad in the corner if anyone finds a better window seal let me know i dont mind paying more for a better fitting one

Lee H · 08-24-2012, 06:12 PM

Video would be great. I'll be doing this very soon. New precision gaskets, original trim, and after market glass. What rope do you guys use and where can I get it?

This is a standard rope-in tool that's used in the auto glass field.
