Circle D makes a nice one. From what I remember when putting mine together, the converter needs to be made to work with the th400 (longer hub) to ls swap or you have to use the spacer.

Is your converter made to go from TH400 to LS or TH400 to SBC? If it's made for SBC, then you'll need the spacer.
