The Stovebolt Site Forums The Shop Area General Truck Talk 1949 3100 1/2 ton side vent door.

My truck just did a disappointing thing to me. The side cowl vent bracket that is welded to the side of the truck just broke off from the body of the truck. Now the vent rattles around. Want to fix it without damaging the paint. Has anyone had this happen and how did you fix it? JB Weld? Will it hold? Please let me know.

Recommend remove fender & do it right

Not a big job and you'll feel better about yourself

Exactly where did it come apart? Pictures would help. As far as removing the fender, I am having difficulty understanding how that will help with the cowl vent.

I agree Carl. There is a firewall between the fender and the vent.

OK, I got my side vent door bracket remounted using small #4 stainless steel screws ans tapping the threads so the bracket would accept the screws. Now another problem.
Installed the door and handle and the door won't close all the way. Now I know how the spot weld got broken! Someone thought it would be funny I guess to bend or overextend the vent door until it broke! Got to really watch at car shows!! Anyone got any ideas how I can get the door and lever to work properly? Any on have a picture of the side vent assembly? Checked my shop manual but nothing. Checked the assembly manual, again nothing. Any suggestions or HELP would be greatly appreciated!!

I have pictures of several here. If you need something else let me know I have a couple spare assemblies around. If you are using a new gasket they are not quite the same as originals and it takes some time for the door to close tight against it.

They can be a pain to adjust to close properly. Keep trying, you will get it to work and not know how you did it. I have a spring loaded version on a 49 and I can't even get the bolts started to put it on. When I think I'm real close to getting a bolt started, it snaps closed like a bear trap.

Hey 52 Carl, I'm putting a 50 GMC truck back together, owner pulled alot of it apart before I enhearited the project. But 9 grand later I've gotten to the doors and putting in the window channals, (all new stuff). A thin rubber strip with one side reased edge, I think goes in the top between upper door frame and channal. Tried differant ways but no matter what, it getts in the way of the inner trim frame mounting screws.
Not realy sure if this is that right way to post this put its worth a try. I work like 24-7 and do alot of project vehicles along with running a bussines. So projects are mostly night & weekends. This truck is one of many that I have done restoration work or customizing on. I had to rebuild the frame and give it a nice 4 air bag lift susspension. its got a 88 1500 GMC rear frame and front Sussp. Parralell rear sussp I put on it really gave it some up & down range. Oh well, My door gasket problem needs to be figured out, dont wanna leave it out. I'll hang for another hr to see if some one can hook a brother up.

Well, I have figured it out. the reased edge goes against the out-upper molding inside the top and contours the channal. Then the inner mtrim sandwitches the channal in place. Ya'all keep-um straight out there. See Ya.

I have a 1947 3100 AD PU with the side vent with the knob and 'fiber' gasket as shown in Brad Allen's pictures. I also have two holes in the vent door. I'm thinking it was for a cowl antenna. The truck has/had no radio. Can't imagine the factory pre-drilling holes for no reason. I was ready to weld the holes shut and metal finish until I saw those pictures. Anyone have any insights for these holes?

Never seen or heard of holes in the vent door for anything from the factory..... but then, I haven't seen everything. I think a previous owner did it...perhaps to put an antenna on it?

Do you still have a drivers side spare assembly cowl vent available?
