Rob,... I don't have a miata she'll but maybe something better.
Before I got back into wheeling I was autocrossing with the scca. Long story short, I have a completely rust free 93 240sx roller in dry storage. Straight body, never hit, and I have a dark grey interior, brembo rotors, sparco suede wheel and shift knob, plus a little more. I've heard clean dashes trade for 250 or more for these things now and mine is mint. Also has a welded in s&w roll hoop and rear strut stiffener. Spare harness to swap the windows/locks to power. Factory service manual. I'll let it go cheap I was going to do the ls swap myself but the jeeps are taking over my land and life. I'd be flexible on price
