I’ve actually built one IF can from scratch. I did it by placing to axial inductors side by side. The “primary” inductor will induce a signal upon the “secondary” inductor, just as these coils work in the original IF cans. You’re lucky here that it’s the second IF can; I personally dreaded the thought of trying to reconstruct that third IF can while I was restoring my own 46-480.

Have a look at what I did to build an IF can: Philco 49-906 IF Can

You’ll need to create two paired inductor circuits, one for AM and one for FM. For each one, start with your known capacitor value. Using the formula 

    2*pi*f = 1 / sqrt(LC)

we find that

    L = 1 / ( (2*pi*f)^2 * C )

where L is inductance (in Henries), pi=3.14, f is your resonant frequency (455kHz for AM or 9.1MHz for FM; convert to Hertz), and C is your known capacitor value, in Farads.
