Maybe a silly question, but do both Modern Driveline and American Powertrain market the White Lightning? Who actually makes it? I bought mine from AP but to date it resides in a box for Someday.

Short story - The Hurst Blackjack and the White Lightning shifters were designed by the engineers to be used in the rear mounting position. They must have over-looked the fact that if mounted in the forward position the shifter pivot is directly over the top of one of the larger gears in the case which slings a lot of fluid. In the rear position the Hurst shifter was fine (a little residual around the ball, the White Lightning leaked enough that fluid was on the cover and after probably 2K miles would leave drips on the ground.
Shift action on both was good, there was pro and con (very nit-picky) differences with both with shifter location, throw length, gate width, spring tension, feel, etc. Overall fit and finish of the Hurst piece was better.
I worked closely with Jim Goodlad at Hurst Drivelines submitting internal and external photo's, external video showing the leaking, I also made a plate with gauge to pressurized the case to show it wasn't building excess pressure. Thanks to the input from others and myself Hurst took action and has re-engineered the shifter to incorporate a seal. It's not a fast process but the new shifters should be ready the first of February.
Regarding the White Lightning shifter I was told on the phone by two American Powertrain key people that they personally designed the shifter and there was no was it would leak like the "inferior" Hurst shifter. Identical situation and tests.......the White Lightning leaked twice the amount. Their resolution was poor communication (ignoring) and finally sending me a used Tremec shifter with their adjustable shifter pivot for my $300 investment and inconvenience. Not surprised since American was started by ex-Keisler employees. FWIW - I had ordered and paid a deposit on the Keisler RS600 but it started smelling fishy and canceled.
Hurst on the other hand has went above and beyond the call of fair customer service, they've exceeded expectation and then some.
