Re­plac­ing and ad­just­ing the vent win­dow on a ’67 Ca­maro re­quires a lit­tle per­sis­tence and pa­tience

As with many projects, you start down one re­pair path and end up go­ing in a dif­fer­ent direc­tion.

We’d never re­paired a vent win­dow as­sem­bly be­fore, so this project was a com­pletely new ad­ven­ture. The first or­der of busi­ness was to read the in­struc­tions … which don’t ex­ist. The best thing we thought to do was to search the In­ter­net for tu­to­rial videos. Af­ter view­ing a video for a ’67 Fire­bird vent win­dow, we got an idea of how the win­dow comes out of the door. The rest was up to us to fig­ure out.


The bot­tom of the driver-side vent win­dow was ex­tremely loose. It seemed as though the nut and pivot ten­sion spring at the bot­tom of the vent win­dow were miss­ing, so we called Na­tional Parts De­pot (NPD) and or­dered all the parts to re­build the vent win­dow as­sem­bly.


Peo­ple said that re­mov­ing the door glass was re­quired to get the vent win­dow as­sem­bly re­moved. We didn’t want to do that un­less it was ab­so­lutely nec­es­sary. Ad­just­ing the door glass isn’t fun so we didn’t want to mess with it. We found two Phillips screws, that when re­moved, al­lowed us to slide the win­dow glass all the way to­ward the latch as­sem­bly. This gave us the room we needed.

The ex­ter­nal win­dow felt had to be re­moved in or­der to re­move the vent win­dow as­sem­bly. We got a lit­tle rough with the win­dow felt and broke one of the clips. Great! An­other part to or­der from NPD. With care, it should be able to be re­moved with­out break­ing it.

Once we re­moved the vent win­dow as­sem­bly, we could see that the nut and pivot ten­sion spring were miss­ing be­cause the lower half of the pivot stud had bro­ken off.

This posed a new prob­lem be­cause the parts we or­dered were to re­build the vent win­dow as­sem­bly. Since the stud was bro­ken, it was nec­es­sary to re­place the vent win­dow frame chan­nel. No­body seems to sell just the frame for the glass sep­a­rately. NPD in­formed us that they sell new, com­plete vent win­dow as­sem­blies.


Un­for­tu­nately, they were com­pletely out of stock on the com­plete as­sem­blies with clear glass. The only way to fix it in a hurry would be to or­der an as­sem­bly with green-tinted glass and swap that with our clear vent win­dow glass. How hard could it be to re­move a good piece of glass from both chan­nel frames and in­stall our orig­i­nal clear glass in the new vent win­dow chan­nel frame? It seemed like a good idea … at the time.


Since we were re­plac­ing a part that was already ad­justed prop­erly, we had a lot of the work done. We set all the ad­just­ments based on the orig­i­nal win­dow. If you’re start­ing from scratch, you’ll need to con­sult a fac­tory ser­vice man­ual to ad­just the door glass.

Luck­ily, the project didn’t snow­ball into an en­gine swap or new floor­pans, and we even learned a cou­ple of things. In the end, the jour­ney was a lit­tle frus­trat­ing, but we got to the same des­ti­na­tion and now we have a vent win­dow that works and the wind noise in­side the car is gone.


Do not at­tempt to re­move and in­stall the vent win­dow glass from the vent win­dow chan­nel or in­stall new glass into the chan­nel un­less you’ve dis­as­sem­bled the chan­nel frame from the vent wing as­sem­bly. The pivot points on the chan­nel frame are not de­signed to take the abuse re­quired to in­stall the glass.

Tape the glass sur­faces to pre­vent scratches. The tape also gives a small layer of pro­tec­tion against break­ing the glass while work­ing around it with tools. CHP

02 | We thought we were go­ing to re­build our orig­i­nal vent win­dow as­sem­bly, so we or­dered all the nec­es­sary parts from Na­tional Parts De­pot (NPD): seals, ad­justers, han­dles, vent win­dow studs and re­build kits, and door panel clips.

04 | We used an X-Acto knife to cut the seal out of the win­dow chan­nel at a steep an­gle. We then used a com­pos­ite scraper be­tween the glass and the chan­nel to give a lit­tle lever­age to work the glass out of the chan­nel. Wedg­ing a metal tool against the glass will cause it to shat­ter.

03 | We re­moved the door panel then rolled the win­dow down to the bot­tom and re­moved two screws from the long hor­i­zon­tal chan­nel, which al­lowed us to safely drop the win­dow and slide it to­ward the door latch. It was nec­es­sary to re­move the ex­ter­nal win­dow felt to get the vent win­dow as­sem­bly out of the door.

07 | To re­move the vent win­dow han­dle, be­gin with tap­ing the glass to keep it from get­ting scratched or bro­ken by a tool. Place the han­dle on a wood block and tap the roll pin out with a small drift punch (see ar­row for direc­tion). The wood block is used to sup­port the han­dle and keeps the glass from break­ing.

01 | The vent win­dow would not close with­out push­ing the win­dow into place man­u­ally and the old seals were in bad shape.

06 | The green-tinted glass (left) is subtle. The non-tinted glass (right) is com­pletely clear. Be­fore or­der­ing any glass for your Ca­maro, make sure you’re or­der­ing the right type of glass.

05 | For com­par­i­son, the orig­i­nal pivot stud (left) was bro­ken. The new OER as­sem­bly (right) from NPD is com­plete, with the ten­sion spring.
