If you use the std tamiya upper shock mounts the shocks rub against the tower in the rear inner positions. Enlarging the TRF upper cap to accept the xray shock pieces pushes the shock body far enough away. The fronts work fine without modification, I did it anyway so the shock lengths are the same all the way around
