Value and VIN location on 73 Duster with fold down rear seat

Hello all,
I know VIN’s have been discussed and I’ve searched the topics. I’ve seen that the VIN’s for Dusters can be found on the Rad support and the rear speaker deck shelf, driver’s side. I’m going to look at a 1973 duster that has the fold down rear seat and from what I’ve read this might change the location of the VIN in the trunk area. I want to be very careful because the vehicle is a 73 and has been switched over to a 71 front clip and tail light section, want to make sure the VIN wasn’t just tagged on the dash for a 73 title. Not to sound stupid but just how challenging is it to get into position to see the VIN in the trunk area? Any information would be greatly appreciated.

Additionally, if the car was a 73 and restored to look like a 70 or 71 how do you feel this would affect value. I’m not looking for numbers matching and know I should not expect to pay numbers matching prices. Looks like it was a slant6 or 318 car switched to 340. Don’t beat me up, condition is everything and can be subjective. This car looks very clean on the exterior and only minor blemishes on the original interior. Please share your opinions.
