I have this standard cab wing vent which means it is painted black not stainless. I have had it for at least 17 years. The metal is good. The glass is the original FoMoCo and is in good shape. However, the pivot is broken off:
Question: can the glass be taken out intact so I can put an pivot in and then replace the glass? I seem to think not. My buddy says maybe you can heat the vent and then pull the glass out. I think that would crack the glass.
It would be nice to have FoMoCo glass in the vent. I am a stocker but I am not so ****-retentive that I have to have original glass.
Yes, it is possible to get out without breaking. Like Doc said you definetly need a lubricant in the channel. Let it sit for a bit then gradually pull it. Be careful not to put too much pressure on the metal as I've found the hard way, sometimes the glass will take more pressure than the frame.
I did exactly the same thing a few months ago. Overall, it was not a bad experience, or put another way, I didn't break anything and eventually got everything back together and working properly. Work a penetrating oil or mineral spirits gently between the glass and setting tape using a thin putty knife. Heat doesn't hurt, but don't overheat the plastic between the two laminated glass panes if the glass is going to be reused. The trickiest part for me was finding a way to hold the frame securely to some sort of anvil when you hammer the flare in the top of the rivets that secure the pivot. I found that I had to increase the depth of the recess in the brass rivet ever so slightly to get it to flare enough to tightly hold the pivot. I do not know if this problem was something to do with the rivets or the flaring punch. The flaring punch and rivets that I used I bought from Mid Fifty. Also, I found that I had to file the rivet head a little bit to get it to sit nicely in its hole on the outside of the frame. This also helped get a solid riveted connection for the pivot. I used mineral spirits to lubricate the setting tape for the re-installation. I found that I had to keep the glass pushed in tightly into the frame with electrical tape until the mineral spirits had time to dissipate. Without something to hold that glass tightly in place, it tends to want to squeeze out of the frame a bit. I learned that if the glass projected out even a little bit (1/16" ) past any metal ends of the frame, that the vent windows will not close properly. Once the mineral spirits had evaporated out, the bond between the glass and the frame was very strong.
Thanks for the tips, guys. I have been trying to sell this at swap meets for several years with no interest so I thought it was not possible. But maybe I am one of the few that do not want the bright metal trim where it doesn't belong....
It is raining today so maybe I will try it today. Will let you all know later.
I just dropped mine off at the glass shop yesterday for the same problem. I bought the setting tape from MF and a single layer was too thin, double too thick. Instead of monkeying around, possibly having future issues or waiting for the correct tape to come from somewhere I figured I could be at home drinking beer and knocking a few more items of my list of (now) less than 7,991 things to do. :-)
Had the shop remove the vent glass (it broke when they took it apart), replace the pivot (my part) reset it and the door glass. $50. Happy to pay them for it and knock off two more items from the list.
Replaced those items, installed RH vent seal, repaired RH window crank that fell off every other day, re-hung hood and front clip, fixed cigar lighter, reinstalled cowl vent seal (why does everyone think that's so difficult? PO installed it upside down. 3m 8005, thin line on cowl and seal, spread with toothbrush, have a beer while drying then install. No clips, clothespins, cussing.), mow and weedeat, wash and wax truck, throw on cover just seconds before thunderstorm rolled through. Only 7,980 things left on list... ;-)
