New guy-1959 Apache questions

[Grape Ap(ach)e]

Greetings fellow truck fans.

Long time lurker with a 1959 Fleetside Apache. Getting serious now on working on it.

I have read through a lot over the years, but still have two questions and decided to finally ask.

(1) Does anyone sell a bolt on IFS kit? I've yet to see one.
I really don't want to chop the frame up...

(2) What made a truck deluxe? Exterior and interior?
My understanding is (a) the interior was chrome knobs and the deluxe heater control and (b) the exterior was chrome bumpers, chrome cab trim, chrome windshield trim and the infamous bed side trim.
Would be nice to see a schematic.

We all know it is rather impossible to find the bedside trim.
I see that someone makes the end pieces as reproductions, but what about the long strips? Does anyone have some original strips for sale?

Are there any obsolete parts places or people that are worth a try to call for the bedside trim hunt?
