After pulling back the carpet in my E30, I was greeted by a good amount of floor pan rust. Three spots are rusted through, while the rest was luckily just surface. On the passenger floor pan, I cut out what I wanted to remove and then realized that I was cutting within an inch of where the Transmission Crossmember bolts on. Should I cut as close as I can to the edge of the rust, or will this compromise the integrity of the trans support? My other option is cutting out the area where it mounts and then drilling and tapping a new hole.
Additionally, there is a spot of rust on the passenger side of the transmission tunnel about the size of a quarter. I punched it through and it looks like there are two sheets of metal there. How can I patch this without dropping the trans?
Pictures aren't great, but I won't be home with the car again for two weeks so they're all I have for now. The hole on the trans tunnel can just barely be seen in the pictures.
