can anybody give me a little bit of help.
have had kitcar built for 5 years and now want to change steering column. have had sierra column in but now trying to refine it by using propper bearings and quick release hub. which center stem can i use steering rack is escort mk 2 so i need one to match up with it.

There's not much wrong with the Sierra column imo. You can easily put a QD hub on it and a spherical bearing on the lower part, making eveything nice and smooth.
