Hi all, I bought a 1984 280ZX few months ago. Enjoyed autumn driving and am now starting to do some works. Any suggestions 1. For sealing water leak from the targa panel. Mechanic suggests that the rubber needs changing. Any advice where to look for targa roof and door rubber? I want it sound proofed a bit more and change seal on all doors. What should it cost? 2. Speakers, audio system. I plan to keep the original cassette player. It has another empty slot. Can I put a new system. What should I look for size etc. 3. Rear wiper moving a few degrees and stops. 4. Dash lights coming on randomly and when accelerating up with voltmeter for battery going of the scale. One mechanic mentioned that electric relay box in steering wheel needs changing. Anybody had it changed? where to find one? Thanks and happy driving.
