How Fix Rack'nPinion Steering

[CarlSereda@aol.com]

Hi List,
New or good used TR4 Rack and Pinion parts seem to be hard to find. My 
steering assembly is in great shape except the rack (rod with teeth) and the 
pinion (shaft with gear-end) . Anyone know where I can get those two parts 
either new or used? All else is ok (do need couple shims to tighten up rack 
ball joints too).
