I am starting to lean towards the front door alignment and seals, as I can't find any trace of water running down the inside of the firewall anywhere, but I have found moisture on the bottom inside the seal area of the front doors. Looking at the front doors they have dropped slightly, and I think there maybe a small gap at the lower front edge between the frame and door in the guard area. I put new door seals on last year, but they were aftermarket ones and I dont have much faith in them, might look at getting toyota ones if available and if reasonable in price....

Is there anyone else out there with a 60 that has had or is suffering from this same issues?
At the moment I have my cruiser in the shed doing a rebuild, front diff, suspension, motor and box are out, for reco. (should have the block, crank, rods and head back today). So I cant really get it out side and hose it to test it. Also, whilst the engine and box is out it would be easier to fix a leak from the engine bay area, if it were from there....
Any suggestions??
thanks,
