1992 4x4 Interior Water Leak

[shawn666999]

I have a 1992 Toyota 4x4 Extended cab. There is rivers of water coming into the cab from both sides of the truck. I pulled back the plastic moulding and used a hose to identify the leak. I know it's not the windshield seals. If I put water over the wipers into the wiper grill and around the hood, the water pours in. My floors are always wet and during heavy rain there is an inch of water on the floor. I worry about the computer module on the passenger side and the Fuse panel on the driver side. Water comes in right behind them from up above.

I know there must be some rust and rot somewhere. I need to stop the water. Any advice on where a body shop should focus on and would this be a huge job? I assume the fendors need to come off. I fear the holes may be hard to get at.

I need to keep the truck going for a few more years.

Any help would be appreciated.
