The REM37BY is a shorter version of the REM40E. It also apparently
runs cooler.
Googling around, I see there may be a shorter version of the REM37BY.
Doesn't sound correct; I'd expect a different model number. Can anyone
verify or counter a 'shorter version' of the REM37BY?

Once the old stock of longer plugs runs out, the shorter version will be the
only one available. The short version is .620" shorter.
