My 2 '69s with the performance hood paint and no AG both had black ribbed inserts - never seen red ones. My '69 AG RR had double screens, reddish-orange in color, woven style. No hood stripes. All 3 were St.Louis cars. Never seen original black screens or the "flat" screen style referred to earlier. The woven screens appear fairly flat on their backsides, though. IIRC, all 3 of my '69 RRs were fairly late production; for sure 2 were.
