Does anyone know the specifications for the following components? :
1. Choke L2 which connects to primary of input transformer:
a. DC resistance and Inductance(Henrys)
2. Input Transformer to Push-Pull Circuit:
a. Primary and secondary impedance
b. Primary and secondary DC resistance

The entry on this site under Resources for "Clarion/60" gives the DC resistances for these parts.

For the audio interstage coupling transformer, it will probably be 1:1 so the input characteristics will determine the impedance of both windings. Basically you are matching the plate circuit of a type 24 tube. I don't know what this is offhand, but it is probably in the several Kohm range; maybe even over 10K. Presumably this can be determined from a Type 24 tube datasheet.

The L2 inductor impedance (DC resistance: 2K) would have been selected to work with the two electrolytic caps in the "pi" filter circuit to have a network impedance peak at around the full-wave rectified DC pulse frequency, which is 120 Hz for North American power. This provides maximum hum suppression. You can calculate this from the impedance equation for a CLC pi network with a center frequency of 120 Hz. My guess is that it will be a couple of Henries.

Sorry to provide mostly "soft" information but I suspect that hard data on these impedance parameters will be difficult to come by. You may luck out and find a restorer who has actually measured the values of these parts, but that's probably a long shot.

BTW, I apologize for conflating "inductor value" with "inductor impedance" in the above text.
