They are still selling the mounts. Here are the mounts I bought, and they move the motor forward 1.75" inches to make room for the SRV solenoid, oil filter adapter and AC compressor on VCT motors.

And you are correct that it's spool mount or nothing.
Ah, track mode. My 2015 Challenger R/T only had Sport, so missed that was even an option. Thanks!
