I also installed the same TS-G1645R speakers in my 97. The front speakers went right in without spacers or washers and does not interfere with the full operation of the window. The bar for the window track is directly behind the speaker, but it did not interfere with the installation at all.
I did have to bend the tabs up in the speakers a bit so that it would fit flush with the contour of the door. Here is a picture with the tabs that need to be bent forward shown in yellow.

I know, I know... relax about the screws. I’m sure after a few years that they’ll vibrate and rip the speaker. When that day comes, I’ll spend another 35 bucks and replace them and use smaller screw heads next time.
Here is a picture with the door cards back on. There is no gaping or other fitment issues.

Cool thanks, that helps. My Aussie 80 has no speakers in the front doors.
