Lower Windshield Cowl Removal?

I'm replacing the lower/upper windshield cowl panel and both inner/outer shoulders. I got the outer shoulder off drilling out the spot welds. It looks like the lower windshield is overlapping the inner shoulder.

  • Do I need to remove the lower/upper windshield cowl panel first before removing the inner shoulder?
  • Looks like there are two spot welds on the inner shoulder, on the firewall top side holding it to the windshield cowl panel. Is this the case?
The yellow point to potential spot welds holding the inner shoulder. The green are potential spot welds holding the lower windshield cowl. Looks like I might need to drill these out from the bottom. Thoughts?

Re: Lower Windshield Cowl Removal?

Pretty sure I just hit the spots under that piece with impact chisel then grounded it flat on underneath. Putting on my new one I got aggravated and cut that little piece off. FYI my replacements of inner cowl were shorter at the top where it meets the pan by at least an inch.

Re: Lower Windshield Cowl Removal?

Kaizan, Thanks! I got it off. I drilled out most of the spot welds but a couple were not where expected. I wonder if the factory welds were manual.

I have a good bit of rust on my inner channel. I might be able to fabricate repairs but either way, I believe it has to be removed first. The 2nd picture has rust holes.

Any ideas for getting this channel out? At that point, should I repair or replace?

Re: Lower Windshield Cowl Removal?

wow that looks like mine. because mine is not an ss or anything special I'm trying to keep costs down. that pan piece is expensive so I'm going to just repair mine. its mostly covered so doesn't need to be perfect. The windshield channel is replaceable just by itself which is what I'm going to do.
yes the spot welds were manual. on my car I've seen quite a few double taps that a machine wouldn't do. kinda cool though when I think of that person in the fisher plant making this 45 years ago and he was the last person to touch that spot weld.
Hey I had another post asking for pictures of the windshield channel that I have to replace. I have nothing left to see. can you post a pic maybe with measurements of how the dash/windshield channel/cowl tray come together?

Re: Lower Windshield Cowl Removal?

yeah can you measure how deep the front and back are? close up pics would be great. my dash is rotted along with that piece so trying to determine where it attaches to the dash. not sure how much play the windshield has. don't have one on hand. would hate to do all this and have the windshield not fit.

Re: Lower Windshield Cowl Removal?

I'm a bit confused. That part is part of the dash - it does not attach - it's a solid piece. I can't get to the rear. The lower cowl panel is in the way. I'm either going to repair mine or replace. I'm just concerned if the filler will show through after I weld in new metal.

This is in the center near the dash speaker.

Re: Lower Windshield Cowl Removal?

awesome thanks. this is the replacement piece. I assume it attaches at the top ridge of the dash where it slopes down. too busy to get it right now but i'll put it up on my other thread when I get it going. its not complicated but the arc of it could be not worth the work when its so cheap to buy.

Re: Lower Windshield Cowl Removal?

I used that part that Terrence posted above from GU, its a nicely made part and the shape is perfect. The only thing I did was to cut off most of the two end " dog legs" that I did not need which saved a lot of work.

Don't cut ANY of the top of your Interior Dash off until you get the repo part and as I might have mentioned in an older post to Terrence thing about using epoxy to fasted the repo part to the top of your dash.


Have Fun, Tony

Re: Lower Windshield Cowl Removal?

How does the dash frame attach to the lower cowl channel? I'm not seeing any spot welds from the top.

Re: Lower Windshield Cowl Removal?

Mine is too far gone to see if the dash is spot welded to the other two pieces but I did see spots on the lower side of the three pieces. So the dash, tray and tray top are sandwiched and welded at the front edge. The dash has to be spot welded there as there is no other way to hold it down. Interesting I found a hard rubber seal between my dash and the other two pieces in this groove

Re: Lower Windshield Cowl Removal?

Yikes! I went back and I think I found the spot welds.

Mine is bad like that too. Don't let it get to you. You'll look back on this day and days like it when your car is complete and looking like a shiny new penny.
