Leak!

[AlleyCat]

right ever since i got the floor pan welded up (a few months ago) every time it rains, and the cars been sitting on my drive for a few days, i seem to acquire a small lake in the drivers side rear quarter.

nothing on the passengers side and nothing in the drivers footwell. i replaced the rear quarter window seals about 6 months ago so it cant be them. and i cant locate any rust holes from the boot into the main cabin.

i am aware the rear window does leak (even though that seal is brand new too) however its on the opposite side to where this puddle ends up. plus im sure that just leaks through the speaker and into the boot.

any ideas or suggestions?

thanks

Sit inside while someone sprays the car with a hose (or just wait until it rains again) and see if you can spot where it's coming in?

No other suggestions I'm afraid
