Ignition coil - '99 LX versus LC - different part numbers and prices

[SteveH]

1999 Land Cruiser ignition coil lists for $156 and a 1999 LX 470 coil lists for $121. Both different part numbers, but the engines are obviously the same. I bought a Denso from Rock Auto for $51, so I didn't buy either of these OEMs, but can anyone speculate why there are 2 different part numbers?
