rsx84,
The grill is the 'prior-term' to quote babelfish/r30.co.jp, is identical to all the early DR30's.
And sorry, yes, the strips of rubber between the front door window & rear window have been claimed by StageFumer11.
99% of other parts are available, if it comes to wrecking it, I will strip what I can and put it away in the garage. The price of early RX stuff is going ballistic, I guess the demand will outstrip supply soon for R30 stuff.
