Make up a couple of extensions for the back lines(steering lines) by the sounds of it if yor bar is at your fingertips with the depower pulled you will need about a 300mm extension with 3 knots spaced at 50mm intervals ,easiest to make it with a figure 8 knot at the line end and a set of 3 granny knots the other end ,make sure that both extensions are exact when tensioned ,all knots equal, or you'll get a steering inbalance,try it on the furthest knot first and work backwards,ideal will be about 50mm away from the stop when all four lines taught and no depower pulled.
TD2 bar was also 2-1 reduction so once you sort the lengths it should work fine.
