Older gen topper fitting 2019

[Rich51]

I was wondering if anyone knows if a Leer topper from a Gen 4 5.7 bed will fit a 2019 5.7 bed? I found one on craigslist for a good price but don't want to waste money if it won't work.
Any help would be great thanks, I couldn't find a post on here with the answer and hopefully I didn't over look it.

I found when fitting the extang tri fold from my 2014 to my 2019, the beds are shaped different. The pre 2019 beds are wider in the front than the rear, the 2019s are straight. The cover did fit, but just barely. They both had 6’ 4” beds.
