Wilwood and the Spindle confusion

Sup,

A few months ago, I did mention on the FABO forum that I'd buy the 140-11019 or 140-11019-D Wilwood kit for my 1974 Dodge Dart "Hang 10".

I've seen many posts about SBP/BBP, Disc Spindles, Drum Spindles, up to 72, 73 and up, 2" drop spindles, etc., etc., etc.

Initially, I checked on Jegs and Summit for that kit and, both would say it fits my Dart... Then a few weeks ago, when I checked again, Jegs suddenly mentions "2 inch drop spindles". So I go on Wilwood, check the product directly... it says "magnum force 2 inch drop spindle". I go on Summit, it only mentions "disc spindles". Even the instructions PDF on the Summit website never mentions anything about a "magnum force 2 inch drop spindle".

So I check the spindle in image... I check various websites and I notice that some parts websites list a specific disc spindle as A/B/E body Disc spindle...

Wilwood says it doesn't fit (e-mail) but I'm kinda skeptic... Not in a "I don't wanna acknowledge it doesn't fit" but rather "Why does it suddenly not fit anymore when the previous instructions shows it fits ?"

Anyway, if you have the 140-11019 kit installed, can you confirm exactly which spindle you got on ?
