Here is a rear flange for the TD and TF gearbox.  It comes with the original hex nut, washer and the spacer (distance piece) for the main shaft.  All the parts have been bead blasted and are ready to use.  

The flange is no longer available from Moss Motors.  The little hex nut is available at about $35 each. Hard to believe.  You get all these parts for about what the nut would cost.

Be sure to look at my other gearbox listings.
