looks nice, the big money on these is for the good original metal ones or restored with documents of work ie pics before paint
this one does look cool and nice and if put together as nicely as pics look to someone it is worth 28K
using bedliner type products has been done by people to cheaply cover up rust and make a vehicle with problems look nicer, got pics of it before bedliner then to a more educated buyer that helps show its not rust holes under. This truck pictured has bedliner over the outside areas where rust is so common its guaranteed to be there unless the truck lived an easy life. in cali a poorly done 350 swap 40 is probably going to fetch 10k since common out there, this one is clean from the pics i see it looks respectable and keeps the classic 40 look
ive seen ones with similar motor swaps but done poorly with 30- 40k obo in the window locally, they sit a long long long time and pop up on craigslist and eventually change hands a few times. for your part of the country i see alot of "restored" 40s pop up from south america entering the country making buyers more skeptical of them from that area so you may want to make note you are not an importer or business
it looks nice I would start at your price of 28, it only goes down
flip that bezel
