Thanks for the information. I haven't put the RDA7934S on the front yet (bought them for $90 so I might lean towards the new design for everything.

Is the new design and materials that RDA are beginning to use better than the old in terms of durability? Less rust?

Are there different part numbers? Cost differences? And last question, when will they be available?

Thanks very much,

Sam.
