Is the top on an 84 / c4 suppose to have any weather
stripping attached to the bottom front edge ?
the reason I ask is that I just had two windshields
installed. The second was the result of some advice that Dad
gave me here on this group about the installation procedure.
even after the second installation,
the top seems to bow just a tiny bit in the middle along the
this is allowing water/wind to enter the car.
any advice would truly be appreciated.
Having a hard time trying to figure out where you put the second
On a serious note, both tops on my '90 have weather striping on the
leading edge where the top mates to the windshield support.
Looks like they would easily seal the top even if the gap/bow in the
middle was not much larger than 1/8 inch or so.
Perhaps something is not quite right with the removable top securing
bolts or the seats they reside in?
Tom is right on, there is a seal on the front of the top and the top of the
windshield on the newer tops. If the installer followed the same procedure
putting the second windshield in it could also be installed wrong. The new
sealers, not the 80s rope type, can and will let the class sink in to far
without blocking its travel until it sets. On a nice warm day it can sink to
where the top seal can't stand high enough to completely contact the outer
corners of the top. Then if the top is pulled down to contact the corners it is
bowed up in the middle. During the glass installation the installer needs to be
able to fit the windshield retainers and seals to the contour of the existing
top. When my installer was aware of what had happened he was able to hit the
second windshield right on and it sealed like new. I kept the retainers on for a
full day before removing them allowing the sealer enough time to set as an extra

I followed your earlier advice and told them about the extra

the required sealant but I still have the air/water leak

thanks for your continued help with this Dad.
Can you move your clamping points together on the top and/or apart on the frame,
(don't remember them being movable)? If so try putting some soft but rigid
material under each outer corner, (maybe about 3/8" X 1" X 2"), and latch it and
see if it takes out some of the leakage.
they are not movable. they also don't latch.
top is held on by four screws / two on front edge and two on
back of top.
when the front corners are bolted down that are bottomed out
and seem to fit fine on the corners but the muddle is then
bowed up just a little too much.
do you think that a thin weather strip added to the middle
third of the tops front would help ?
thanks again for sharing your knowledge Dad
I guess I'm rejecting the top bowing in the middle and still think the corners
are to low. You are talking about a convertible aren't you, or was that the
original post? The screw down corners don't sound right. Let me know and I'll
look at one this afternoon. They are having a Sam Hornish day with a parade and
a ton of Corvettes that I can check out.
My car has two tops, one bronze tinted clear glass and one solid
fiberglass top painted to match the body.
Mine use the 4 torx head bolts to mount to the roof, two mounted
vertically in front underneath the sun visors and two in the back
I don't know if mine leaks water as it's never been, and probably never
will be driven in the rain.
I've never noticed any air noise coming from the windshield area, even
at Warp 125. Someday, I'll find a LONG stretch of road and I'll let you
know if there's wind noise at Warp 180+. 8-)
Guys, remember that the frame and body attachment pieces changed around
'87, give or take a year. Appearance is much the same but early tops
can't be used on later bodies without swapping some body parts.
'84 and '90 are different in minor details.

From what I looked at last night on the C4 and assuming that your top fit
correctly before the windshield change, it has to be in the way the new glass
and seals were bedded. Sorry, but like I said before after 2 new windshields and
2 new seals it fit as new with no leaks, air or water when mine was replaced. It
leaked so bad on the first go around you could have thrown Walt's cat through
Sam didn't look as good as some of the camp followers did. ;-)
Well, I had the problem before I replaced the windshield.
That's why I tried replacing it.
I am wondering if maybe the corners are being pulled down
too tightly ?
Thinking of trying to put a couple of thin washers on the
corners and see if that will drop the bow from the center a
little and not be too loose on the corners.
I really believe that the windshield was put in correctly
the second time.
although, I do not know if maybe they put the top on before
it was through setting up.
Thanks for all your help Dad
yea, I am keeping the two windshields a secret :-)
my 84 has only one top. it fastens in four places, one on
each front corner and
two across the back. I really don't see how it could be put
the top of the windshield has weather stripping.
I was just thinking that maybe I am missing a weather
stripping along the front of the top
or if putting some type weather stripping on the top would
help fix the problem.
thanks for your response TomC
g'day to ya
