The Stovebolt Site Forums The Parking Lot '60-'66 Trucks Door leaking water top near roof 64 c10

Folks my 64 c10 has issues with driver side. The gap at top of door to roof is too big and water runs inside of cab. I have new door seals and even put some stick on type on door but still lets water run in ( not just a leak)

The lines match on body, the gap is not perfect but not that bad.
The door does not look bent.

Is the door adjustable up and down if I take fender off to get to the bolts?

Any ideas???

I hear you. I have a door that does the same and I have not found a solution otherthan maybe take the door off and reshaping the upper part of the door (which will definitely have implications to the window glass). As is your case, the gaps and alignment on my door is about right and any adjustment will throw things way off.
If you move the door your gaps and latch will not be right and I think that will bother you even more than the water (from time to time).
How much driving-in-the-rain do you do?
I keep the gutter on the roof free of water after a rain to reduce the chance of rust IVO the windshield, which is a prone area. This is where all that water comes from as is drains through your door.
The other side to consider - give that water an easy place to drain. Make sure the drains at the bottom of the door are open and maybe allow for the water that makes it to the floor a path to drain.
I cant provide a solution to your problem. I am in the same pool - so to speak.

I don't drive in rain much and this for sure not a show truck. Yesterday we had some bad weather and I put a old piece of weather strip off another vehicle laid it on top of door and closed it. It stopped that hard rain. Looks like crap but it worked. I'll come up with something and post a follow-up.

Can you give the top of the door a good tug and bend it in a hair? I know this is a GM trick on 80's cars and trucks.

Just do it with the window down.

Are your door seals the type that glue in place or did you change to the clip-on style?
I’ve used both.

Jay - which do you prefer and which one works better for the issue above? I have tried 2 versions of the pinch-on, but I dont notice much change.

I think the pinch on version makes the door harder to close. I’m fairly happy with the glue on style. When I had my doors off I removed all latch mechanisms. Then I aligned the door with the glue on seals. I have not repeated that process with the clip on style, so that might why it seems harder to close the door.

As stated, bend the top of the door in.

Evan, Are you talking about bending the top 2 inch prior to the part of the door with the window channel? Not sure what that part of the door might be called, but I assume just influencing the top bead?
Can you recommend a method? I have 1 door to try this on.

Hambone,

Have not gotten into these doors yet, but on late model chevy doors it was very common to put the window down (You will break the glass if you don't), grab the top of the door, put your hip into the base of the door and give a few tugs. This will bend the framework around the window in just a bit so it closes tighter.

I have no way of describing how much force is needed. Trial and error.

I, by no means, endorse this method, but as a young man a real body man with 60-70 years experience showed me this technique. Open the door, put a 4X4 in place at the door sill and after rolling the window down grab the top of the door and push it in towards the body. You can move the board around to gain leverage in different places to tweak the door where you need it. This method has worked several times in the last 50 years. He explained that the wind, kids, hard usage can bend the doors causing them to be out of proper alignment. Good luck.

Honda civic door seals worked perfectly on my 66 lcf . no trimming no slamming the door. Aftermarket and old original seals dont rebound . Anytime you move or replace a door and leave old seals in place it can cause leaks. Hard 60 year old seals are stuck with there old memory. Left door seal Honda (72355-SVA-A01ZA) right Honda (72315-SVA-A01ZA). Also check caulking in gutter, if cracked causes problems as well. hope this helps Pat66

Who knew? I will try to reshape my door, gently at first. I will let you know if result

I put in new rubber on the jams. They clipped over the metal however that rubber is not close to the door at the top when closed. Tomorrow ill give a go at Tryng to bend in the top of the door but my C10 is built much better (with good ole American steel ) than that go cart in the video link but hey I'll try it.

My wife found a weather seal that may work if glued to upper jam. I'll post a photo of the results of the test.

She thinks my truck and me are like items. Old, sometimes have problems getting moving, squeak, rattle, and a little rusty. However,,,She said if I start leaking, the truck and me are both outta here.

Update:) I went out with my Barney Fife arms and bent part of the top door in a little. (Opposite side of wing). This may work.. tomorrow ill get a few boards and may try enlisting a power lifter friend of mine.

This may just work.

DONT OVER DO IT!

Roger that, I did make it sound like I was going to get mid evil with it. Fully plan on small attempts no way am I risking broken glass or screwed up door. Thanks for the warning ⚠️ though 👍

I finished the door. Washed it today and no water came in.
Took my time. Good nuff

darn, I love my old truck 🙂

Don’t you just love it when old techniques still work.

4X4 is a great tool!
Unfortunately,
Caution is needed with this tool!
I learned the hard way, rolled my ankle on “said” tool this week. Broke my ankle and surgery is scheduled for the 1st!
So much for getting the rear back together or anything else for at the least a month
Anyway, back to the thread, this method also works on aligning hoods also!

Dang, Jim! That's a heck of a way to get some home vacation.

I twisted my knee crawling under the dash with my feet up on the back window while I was rewiring, Been hobbling for 2 weeks. ( I'm not 19 anymore) Good luck with your ankle.

During a blowing rain storm my door still leaked I got some vice grips with the plates on the jaws and bent the top of door in little bit and she's water tight ( as much as I could expect anyway.

I think I'm done with that issue for now.

My cold beer and I are looking for the next Tasker.
