Been a long time, but hope springs eternal, unlike this Spring when we are looking for snow this Friday/Saturday

Anyhow I was doing pretty good with the Grey-Market Model 1985 Scirocco until a 20 year old kid in his brand new Giant Ford truck, on his phone, ran a red light and t-boned (not the Scirocco, phew) us.
It was 09/2018 and the wife and I have had 5 surgeries since then and just trying to manage the basics has been tough. What I hope my last cutting took place in March. Am learning to walk correctly again and trying to make a straight line. A 5# weight limit for now. Oh, he had bare, bare minimum in insurance... grrrr
OK, enough of that!
My question is about some speakers. (This was the Scirocco that was in a barn for 25+ years). Before that someone stole the radio, gauge next to it and two speakers in the 'lift board'(?) in the hatchback.
Could these have been original? Wires still there and holes are 4-3/4" to 5" in diameter.
Any suggestions on what to do to make it as original or of that period will be greatly appreciated!
Thanks Gents!
