Whatever its value, it isn't a critical value. Anything in the 0.1uF to 0.5uF range will help with generator whine in your AM radio. You could even use a distributor condenser.
The AIM calls out a capcitor P/N 1911095 in the RPO section for the radio. Attached is a photo of the aim page and a photo of the capicitor on my 61. The capacitor has the p/n stamped on the end along with 3MF which I believe means 3 microfarads. Now I don’t have any idea what a microfarad is. I belive this information is also in the NCRS judging manual but I didn’t look real hard. Hope this helps! Ps I believe the DR in the center stands for Delco Remy
3 uF is one order of magnitude large than the range of capacitance I suggested. Anyone who wants a correct capacitor needs to locate one like you have. For function and approximately correct appearance, though, a distributor condenser will do. (I think that's what I've got on the generator of my '60!)
I think the 3 MF you see may be a .3 MF. The part number applies to many, many GM vehicles and most used .3 MF. I'd do some more research before trying to find a 3 MF capacitor. I would add, unless you are trying to pick up weak AM radio stations, the capacitor won't reduce "static" which is the only reason to have it other than looks. My '62 radio works fine with local stations and I don't even have ignition shielding. Spark plug wires are probably the greatest source of noise.

0.3 uF seems more plausible to me also. However, zooming in on Leo's picture I'm unable to see any suggestion of a decimal point. Leo, can you look closely at the value stamped on the end and see if there is a decimal point?
Upon request from Jim closer inspection reveals point 3 mf on the condenser on my generator. Old eyes are like old sometimes don’t work as good as they used to 😂
