Cowl Adjustment?
My cowl on my '79 seems to be a bit wider than my hood and fenders. Sorry don't have a pic yet. This was a quick thought and question. I've adjusted the hood the best I can. I have tried to shim my drivers door out a bit. It does meet the cowl better but I think it will not work in the long run with the fenders. They will need to be shimmed out far too much to make it look good. There is something else going on here lol. Can I bend/work the cowl contours? Mine seems to be out too much. I can't see anyway to adjust them. Anyone have any advice? Thanks in advance.

As far as I know the cowl panel is fixed and that is the one panel everyone sets the (fender, hood and door) gaps off of? Maybe some body work guru has a better reply?

The cowl is in a fixed position, the hood/fenders gap is set off the cowl. You need to keep in mind that back in the day any panel gap under 3/4" was considered good to go and sent down the assembly line.
These trucks were never intended to be a "Chip Foose" quality build with perfect 3/16" panel gaps. lol

The cowl can be "narrowed" if need be..... or widened. But,there is no adjustment to do it. It is good 'ol sheet metal cut and weld or cut and add etc. etc. Unless experienced in that type of body work, you need to do what others have suggested ; average everything to the fixed cowl. Good luck,gary

Or after an extended "lunch break" lol. There was some crazy stuff that took place on assembly lines back in the 70's.

Can you adjust the bottoms of the cowl, where it wraps around/down to meet the tops of the fenders? I would think that carefully pushing the bottoms of the cowl inward could adjust it to where you want it.
Is one side worse than the other? Can you post up some pics?

How far off is it? When the hood is closed, does it look to have more of a crown at the center than the cowl? Sounds like the hoods bowed up and narrower than it should be. Spreading the hood would also allow the fenders to move out and align with the cowl. Then deal with the doors. Sometimes these old trucks just need to be bent back into the correct shape. We always had a length of 2x4 in the body shop for tweaking body panels on older vehicles. Put it in the hinge and close the door slowly and it'll push the door out. Under a door to the rocker to tweak it up. Between an open door and fender to pull a fender out. It can even be used to hit with a hammer to spread the force across a panel. Like laying it on top, or the inner edge, of a fender and hitting it with a hammer to push the fender down, or out. These things are heavy enough metal, they can take some abuse.

Ya meangreen I can't post pics, the trucks covered with junk right now. And because it's pushed up against something, I can't see the two sides together.

Shim the fenders from the center bolt on the inside of the fender. The doors can be adjusted from the hinges. Sometimes, if the hood is removed, it will bow a little. You and a strong buddy can try to bend it back out by just pulling from each side, don't get carried away though. My hood was bowed just a little, but I just left it. Like what was mentioned, these trucks were ment to be work trucks, not show quality trailer queens.

I always thought mine was a poor fit/match between the cowl bottom and the top of the fender too. But being as the doors and fenders and such were perfect, and only the cowl stuck out proud of the fender top, I never wanted to really mess with it all that much. You can only change the door to match other components so much before you don't get a good tight seal with the cab I would think.
I'm pretty sure you'd have to do some substantial pie cutting to push that dude back in to meet the rest of the body.
Heck, I'm still chomping at the bit to cut big holes in the cowl, then make the sections I removed detachable somehow so I could easily get in and out of the area under the vent to get vacuum out leaves and debris that get under there.
Maybe one day I'll try to kill two birds with one stone.
