Pinging Slantsixdan, et al: how to find parts to populate a Mopar fuse box?

The original part no. 2290207 has been superseded by part no. 03591596, but even the latter part no. is hard to find.

Grainger seems to have fuse clips that could probably be used (we are concerned with fuse clips for "American glass"-type fuses):

Fuse Clips - Fuse Accessories - Grainger Industrial Supply

Littelfuse has probably the best selection of fuse clips:

102_RE Series - Fuse Clips from Fuse Blocks Fuseholders and Fuse Accessories - Littelfuse

One of the Mopar parts men told me that Napa has a Balkamp fuse clip that is a direct replacement for p.n. 2290207/03591596, with the little ears and everything, but I haven't been able to locate it yet on the Napa parts website.
