After deciding to re-do the instrument panel and get a CNC cut replacement, I researched the options; 1) F-603 is original, discontinued, 2) F-703 is pre-punched, option? and 3) F-6103 OVSZ blanket rectangle with flange.
Tech Support responded that F-703 would NOT work. But I'd ordered it already so I compared that to see the differences, and with some work it could be forced to work. Had also ordered the OVSZ in case, but not here yet.
I'll use the F-703 as a template for shape, make make size adjustments to OVSZ panel blanket to get fit. The pre-punched F-703 has a more accurate top edge curve, and sides, but width is wrong. The pre-dirilled side holes also will be duplicated but in the correct positions.
