i have a 99 A4 car. i have the other tranny out. and i now have a 400,a M6 crossmember,a coverter,shifter,custom driveshaft, and i need to know exactly what size of spacer and where to get it for the converter.... any help would be GREATLY appreciated, cause i am ready to stab it, but am waiting to make sure that everything will be nice and proper.

thank in advance.

 

is the converter for a SBC or BBC and not a LS1. if so, you will need to get a flywheel from a 01+ 6.0L. it already has a spacer onto it and will fit perfect. the older 6.0Ls will not work since the cranks are longer to take up this space.
