bed repair panel kits

[1991 Blue danger ranger]

https://www.lmctruck.com/body-components/bed-tailgate/fr-1983-92-steel-bed-panels I'm looking at this kit online, i need one side of wheel arch and the right corner near the bumper replaced, and in noticing a price difference of literally half the cost for what i thought was the same par. afaik, 88 and prior rangers are identical to the 89-92 ones in terms of the bed, no? so I am asking you guys if you know anything about these panels and if there is any real difference.

I've heard that wheel arches are different sizes. I will say they don't look exactly the same at least between a 92 and an 88 parked side by side.

83-88 beds were a inch-ish longer than 89-92
