Spitfire vs Rotoflex GT6 brake mounting plate

["Mike Ross" <mikeross@Prodigy.net>]

Does anyone know if the Spitfire inner hub, to which the rear trunion is
attached, has the same bolt pattern for attaching the rear brake backing plate
as the GT6+ (ie. Rotoflex) bolt pattern on the vertical link for mounting the
brake backing plate.

I'm considering buying a hub puller designed for the Spitfire, but I think it
will work on the GT6+ too.

TIA,
