A lot of people re new all these parts because they want everything new but if your old parts are still tight then there is probably no need to replace them,you need to remember that you wont be driving your sandman 20000 ks a year and the old parts are probably a better quality than you can buy now.I reconditioned the front suspension on my HT over 20 years ago(probably didnt need to) with TRW parts and it is still a nice tight car to drive.If you want it to drive like a modern car then convert it to rack and pinion.Everyone replaces tie rods,suspension bushes,and ball joints and does nothing to the steering box
