MG MGA - coupe vent window
|My coupe window frames are being readied to install. They had been removed from the car during the restoration, but were not taken apart for replating. The vent window rubber was sourced from Macgregor, and was a good fit. Some trimming is required to get the vent window to close. I have completed this for the driver side (LHD). On the passenger side, the vent window slips into the pivot guide hole at the bottom, and the outside chrome pivot lines up well. However, the window glass is not parallel to the frame channel along the rear vertical side. There is a runout (for lack of a better term) of about 1/8" from top to bottom. The top edge of the glass is not able to close, interfering with the frame channel. Any coupe guys with ideas what the problem could be?|
Have you removed the vent glass from its frame? Since you have mechanical alignment fixed by the top and bottom pivots the frame is fixed with respect to the vertical side.
Did it all fit before your restoration?
You could try resetting the glass in its frame, use thinner sheet material to bed the glass in the frame, the seal supplied by Moss is too thick anyway.
A last resort could be to grind the glass to suit the vertical frame.
I have had all kinds of problems with my Coupe doors and Barney has put some of my solutions on his website.
|Dave, the glass was not removed from its frame. Can't remember if it was ok before disassembly, but the rubber seal was in very poor condition anyway. I'll look at Barney's site, thanks for that tip.|
|I've determined that the Macgregor vent window rubber is the problem. While it fits the frame assembly well, it won't allow for a good fit of the vent window. Ordered a another set of rubber seals from Scarborough Faire. I always seem to have problems with reproduction rubber items.|
How did you make out with the SF window rubber? Did it solve your problem with fit up?
|Dave, the SF window rubber was no better. It was in fact a Moss part, as the Moss number was molded into it. It seemed to be identical to the Macgregor product, I wonder if he makes them for Moss/SF...? I just could not figure out what caused the vent window to sit at a slight angle to the vertical window frame. My only conclusion is that the entire vent window rubber piece is molded too thick. In any case, I did get them to fit with the vent window installed, but there will be no opening of the vent window! At least they look pretty good, albeit in the closed position. I spent too many hours on this "simple" step, had to move on with the restoration.|
