Best Trunk Pan for Duster

I see all different brands of trunk pans. Some are in halves. Some are the whole thing. Which is the best one and best brand ? I appreciate any and all help.

The one piece ones are used when you are replacing the 1/4's, Cant get it in with them in place. The split ones are used when you are not replacing the 1/4's

i thought you could install a one piece pan when replacing the tail light panel ?

Seen guys cut welds out back and lift them up on E Bodies to sneak the pan in. But A Body has deep spare tire well.
Have to remove whole panel.

once again "oldtimers disease" strikes !!!
i completely FORGOT about the spare tire well !
i think i'm loosing what little mind i had in the first place.......................
