What is the trick to getting the doors to seal up at the top corner? I have tried everything and the seals are brand new. I am talking about where the rubber pieces at the top of the dorrs make contact with the seals in the top and the windsheild header. I am going nuts trying to get this thing to seal up! /forums/images/graemlins/angryfire.gif It leaks pretty bad, and I don't want to have to replace the floor! Any ideas??
 
You mean all that monsoon rain we've been getting has been getting ya?!?!

My 72 and my 75 both had leaky matchups............never have seen a full topper that sealed after a few years out in the real world. /forums/images/graemlins/frown.gif
 
You mean it's supose to seal? It keeps me from having to crack my window when I'm smoking LOL.
Beater 74 has good seals. maybe he will post up
 
I just wasted $400 to replace all the weatherstrip rubber on my 73. The pass side door has a 3" gap at the top.

That on top of the fact that my drivers side window fell out & the rear window won't roll up means my inside is soaked. Oh well, maybe it'll be a summer truck. /forums/images/graemlins/rolleyes.gif
 
Both my '73's were sealed very well. My main one I would take to the power wash and not a drop would get it.
I think at one time I may have padded the back-side of that portion of the weather strip a little to make it stick out more.

Neither of the trucks were molested and were in pretty factory condition.
That is before I tore them both down for my project. They were both completly rusted out (Michigan) and had over 200,000mi each anyhow .

I think it's just luck of the draw, my Dad bought a '74 new back in '74 and he said it was in the dealer twice for leaking, and they still couldn't fix it...same story with one of his good buddies...

The door hinges have to be in good shape and adjusted properly. Otherwise the glass won't meet up with the weatherstrip correctly. /forums/images/graemlins/frown.gif My '75 doesn't leak at all on the drivers side, but the passenger side doesn't line up right. When I replace the doors I plan to fix it. (And also finally install the original GM seal set that I bought probably 12 years ago!) /forums/images/graemlins/shocked.gif
 
my 75 has bran new doors from a 76-91 series blazer from lmc and I had to cut them to sixe the top is in storage so I hope I get It right /forums/images/graemlins/grin.gif
 
I have a tiny bit of play in the door hinges, and I did notice that the rubber caps have some wear on them. I will replace those and replace my hinge pins and bushings and see if that will help. /forums/images/graemlins/tongue.gif Thanks guys.
 
I believe the glass is adjustable...

IIRC the glass lever can be adjusted to come closer to the top of hte seal.

They can definately be adjusted on how far up the glass goes.

My problem(s) is with where the door meats the top where all three pieces (door, windshield, and top) meet. I need the two pieces that go on the top, the inner and out weatherstripping. That corner piece IIRC that is part of the inner weatherstripping on the top.

Good luck.
 
you mean those are seals. yeh i wasted $200+ on replacing those hard top seals. my passenger door seals great nota leak but i replace my drivers door with some PEICE OF CRAP MADE IN CHINA DOOR /forums/images/graemlins/angryfire.gif (had to cut the window frame off)i mean this thing won't line up or even come close to fitting, especially where the top of the window frame meets the top. so in other words in leaks like a sh!t. if you have good top seals and your door frame end caps are also good and it still leaks. my guess would be you doors are saging a little and mught need to be adjusted
 
That is where my problem is too. I need to buy the rubber caps for the top of the door. It looks like I'll need to figure out how to adjust the glass to seal up. Maybe I need to replace the window regulators or?? You should be able to buy all of the seals you need through LMC. That is where I got all of mine.
 
where did you get the seals from..i need the little rubber piece at the top of the door just above the wing window...
try some 1" wide grey closed foam weather stripping along the door frame..worked like a charm on my tailgate...

I tried the 1" foam, didn't work for me.... /forums/images/graemlins/mad.gif
