Winshield frame to roof

[blm64Goat]

Does anyone know if there is a replacement panel or frame for these trucks?
Where the windshield seat meets the roof I have some rot and would like to replace. Its at the point on the roof and windshield come together. Thanks.

I cut mine from a donor cab.

if your not replacing the roof then you make that panel or cut it from a donor. be aware that that particular area is different between years so a panel cut from a 47 will not work on a 50. its shaped differently.

A section out of a donor cab would be the simple way to fix it. I'd suggest hunting down an otherwise junk cab that I could cut the roof off or possibly Dave or one of the other premium members has a section of a cab that they can cut out and sell you.

It might help if you take and post some photos of the area you need as some of the guys might be able to come up with other options too.

That's a new one on me, what is different?

I actually have a section of roof I am not using that may have a good one. Of course we have to find out what would be different as mine isn't a '47. But honestly I don't think there is a difference that would matter.

Yuppers, Inquiring minds would like to know what the difference in that area of the cab is. The only differences I know of are the front of the cowl between the 47 and later trucks and the windshield area of the two piece windshield trucks and the 54/55 first series trucks plus the side vent no side vent thing.

There is a lot of differences like the jamb where the striker bolts is different, the '49 and up have a channel for the rubber door lace to fit in where as the early AD had a different rubber held in with a metal trim screwed on. So there are some differences, of course the metal inner panel below the rear window that goes to the floor because the gas tank is under the frame (I have an NOS tank ). But that part up there above the windshield I don't have any idea.

But I sure as heck have been surprised before so I am not saying it isn't different, I have just never known of anything.

I ll get a couple of pic to post later on. I would be interested in what you have getting is the only question? Thanks

[blm64Goat]

I hope I did this right??? Im looking to Replace 2 inches up staring from the edge of the inner front roof brace up into the roof. Down the left post 8 inches and down the right post 4 if possible. I am more worried about the upper than the posts. that is manageable. Thanks in advance.

You don't need the inside, you need the outside?

It does matter and its a big difference. The area where the pinch weld is where the rubber meets the roof has a stepped edge in 50 and later. 47, 48 have a sloped edge, Unsure about 49.

here is what it looks like, this picture has a 47 roof and a 50 pillar post we grafted. it took a lot to get it to look right. Notice the gray roof sloped down and the bare metal pillar stepped

Good info / tutorial. I didn't know that. Thanks for sharing.

Interested in ideas for the best way to fix that rust. Would be less weld area to just replace the roof at the A and B pillars? Maybe more hours that way...dunno.

[dwcsr]

I'd do a roof and the inner brace along with it. The pillars you may get away with just doing the pillar covers. But I suspect that there may be more rot inside the pillar.

Reason for doing a roof is its quicker, looks better when finished, you get no more rust through in that area. With a roof panel costing about $400 shipped, if you keep track of your time it costs about the same for cutting the existing rot out , getting a roof that matches, cut it out and clean up all of it then weld it in and finish the surface. Its way more than $400. The roof comes off in a few hours and goes on a few and next to no body work when your finished and it looks right.

I think that would be way less work than cutting out that whole windshield surround and welding in another.

Just cut the bottoms of the "A" pillars at the sill and then cut the "B" pillars at the tops of the doors all the way around the top of the rear window and take the whole thing off in one piece and replace it with a good donor.

[blm64Goat]

Yes the outside. The inside is the front roof support the 2 are spot welded together

[blm64Goat]

Just to clarify this is a 50 3600 not 47

That is wild, never knew it!

There are a lot of little subtle changes like that every 2 years. Everyone thinks these trucks are all the same, appearance wise they are but each year has a little something different.

[blm64Goat]

Can someone tell then if a 52 or 53 GMC windshield set in the frame same as a 1950 Chevy?
