I need some help with my 1973 Arrow. I'm redoing the interior and replacing the panel plastics that are chipped and cracked. My problem is the lower left plastic trim that fits over the auto- pilot on the left side and extends over to the gear selector and gear lights on the right side. I purchased two and both didnt fit. The holes are off and even with trimming, it won't work. I got one from plane plastics and the other from Piper. No good on both. Anyone has some experience on this?
