Olds extended the glass up and the top edge of the window frame is thicker that the Chevy. So I made a replacement frame. The glass outline is scratched into it.

The "A" posts are at a slightly different angle on the wagon, so this too will be fit into place. The rear door window is where the 5 inch extension will be..

The window is nearly cut through. I will wait for final fit.

After some shimming and cutting I think the rearend position is nailed.

I shoot these pictures at 4MP and resize them to 300x200 for this web site for all you dialup users like myself. Here's a portion of the above picture.

Roughing in the Olds rearend.
