What's that? RT/10 daily driver? I must help...
If it's speaker drip, get some weatherstrip and put it on the body side where the round weatherstrip on the door (circling the speaker) makes contact. Especially when driving, the air flow seems to blow it through.
Look for an odd-shaped rubber "plug" where the forward lower corner of the side window meets the door. On Gen 1, it hardens and leaks.
The forward edge of the top may need another layer of weatherstrip. Air flow may blow the water elsewhere, so this might be hard to locate.
The lower ends of the windshield end up in a "messy engineering" spot. Sometimes sealing under the cowl cover may help.
On Gen 1, the passenger side floor gets wet when the sponge seal for the heater hose dries out. You can see it from the engine compartment - I used windshield silicone glue, which is a very, very runny version of silicone glue, to saturate the exposed sponge and seal it.
While you search for the leaks, the mini-top is excellent. It goes on in seconds and keeps the inside dry. Folds up into a bag the size of two footballs. I extended one hook (catches on the rear wheel fender) with a velcro strip so it fits tightly over the softtop or without any top.
My Gen 1 stay outside 100% of the time, and I've fixed 99.95% of the leaks. The only thing that gets me now is when the side curtain "seal" gets saturated and wicks water through. Have to get more of that tent-silicone stuff...
