Resistance of a conductor is usually stated in ohms/ft or some other length. Voltage drop is stated similarly because V=IR. The length of the conductor in a fuse is very short, its resistance and voltage drop are negligible.

I just looked at a spec sheet for Littelfuse ATO/ATC fuses. For a 10A ATO fuse the typical resistance is 7.7 mOhm. That's under 8 THOUSANDTHS of an OHM. Also, as the fuse current rating rises, the resistance decreases, as expected. A 40A ATO fuse has under 1.5 mOhm of resistance. Voltage drops are therefore negligible, with a 40A ATO fuse having under 60 mV drop in a 12V circuit at full current rating. Hardly anything to even consider in circuit design.

Has anyone successfully installed a Vintage Air glove box in a 55 or 56? That thing seems like it was made for some other car because the angles are all wrong and nothing fits worth a damn. I'm almost at the point of throwing it in the trash and making a new one, but I don't really want to do that if I don't have to.

I follow and understand you on the fuse and ohm readings. But I just have a problem understanding how a fuse and it’s tiny cross section can pass current as well as a big 12 gauge wire would. I have the feeling it’s like a garden water hose with a kink in it. Maybe I’m just dense when it comes to sparky stuff.
I don’t have air in my Nomad. But I did make a metal glove box for it. I hid a Radio CD player mounted in the forward wall of it. Original radio is just a face. No heater/defroster box (perfect weather car only). My windshield wiper motor is reconfigured so it’s mounted under the dash to allow distributor room under the hood.
I just used the original glove box flattered out as a pattern for the metal box. If room is a premium as it was in my 65 Corvette with vintage air the glove box is about half as deep. But I must say V/A did a nice job having a plastic glove box that fit quite well.
ok, But how does the very small cross section of the fuse not act like a small gauge wire in the middle of the 12 gauge wire necessary to flow amperage? Why does it not act like a small section of small gauge wire in the big 12 gauge wire circuit? Because of the tiny cross section of a fuse is not amperage/current choked down? It would almost be like saying the wire cross section has nothing to do with current carrying capacity. Sorry but I still don’t understand.
