Need assistance identifying inductors.

I have an RC car that has fried inductors, resulting in very poor range in the receiver. The only company that sells the inductors as a kit to repair the problem is no longer stocking them.

I'd like to repair the car, but I need to first, identify the inductors and second find a source for the inductors. I am not experienced with buying electornics parts, but once I get my hands on the right ones, I will have no problem soldering them in.

I've attached an image of the inductors. The hashes on the ruler are 32nds... the inductors are only about an 1/8th of an inch long.

Thanks in advance for all who assist me.

My best guess:
L1 is a 56uH 5%
L2 is an 82uH 10%
But, no idea on the other specifics which may be important; such as current capacity, Q, resonant frequency, DC resistance.

Those don't look fried at all, btw... have you taken a resistance reading? They would probably be something like 1-10 Ohms.

Edit:
Here's a candidate for L2: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=M8145-ND
I can't find anything similar to either in stock, though.

I'd rather say:
L1 = 5.6uH
L2 = 0.82uH
Tolerance is not indicated on these.
Same question applies however; how'd you determine they're fried?
