If I recall, RG62 is an air filled ( not to be confused with pressurized)
high impedance coax, I also had a similar requirement when hooking a B&W
sideband generator to a Viking  II,  50 ohm cable was useless when
connecting plate to grid circuits (2k ohm impedance I guess) and 75 ohm was
better but still unusable above 80 meters.

Car radio coax is similar to RG62  I  swapped the old RCA jacks on the B&W
with BNCs , and installed BNCs on the Viking II, then I used premade car
radio coax  extensions from Radio Shack with Motorola to BNC adapters (also
from Radio Shack) It made for a real neat job and works great.
The cables are available in 2, 6 and 12 foot lengths. I cut up  one cable to
go from the circuitry in the rigs to the jacks.
