Hey, '41 Flatbed, here's some advice from a guy who learned the hard way that sometimes going for the cheapest version is the wrong thing to do.
Previous owner of my now fully-restored '53 resto-mod went for the cheap $150 harness/fuse panel by a company called Keep It Clean. We left it in while doing the restoration because all of the wiring worked just fine.
I was on my maiden shakedown cruise when the smoke started billowing from under the dash. I pulled over to the side of a busy highway and put out the fire before any damage beyond the greasy smoke. One corner of the fuse panel had melted.
We then replaced ALL of the wiring over the next couple of days and put in a $500 harness/panel from American Autowire. The quality difference was night and day.
Hope it all works out for you.
Cheers,
John
