Cab corners for my '89

I see them on LMC Truck, eBay, and other bodyshops that also sell online such as Pershing Autobody. Prices range from $19.99 all the way to $99.99. Any real difference between them as far as material quality and or fitment? Just looking for a decent fix to make it not as much as an eyesore.

Also, just wanted to make sure, the new cab corners can completely fix this right?
