AH, The Ole Toyhouse.... Lot of great memories..
Mine wasn't to bad, I did have to repair the drivers side overhang on the inside as it was rotted away..
I finally traced the leak to the front window, specifically the way the window is mounted and it doesn't have weep holes to drain the water that can get in the window frame. (side windows have these weep holes to drain water from the window frame)
Several years ago I placed all my toyhouse forum links on my 2001 Mirada web site. These links still work but you need to first sign in as a member to the toyhouse forums. Below is a link to my 2001Mirada web site that has the Toyhouse links..

One of the advantages of doing my own web site vs using a forum to document work; the forums can go away or get deleted or I can't edit , etc, etc, etc.. With my own web site, I have complete control, with no restrictions.
