My cousin is junking his rustbucket '84 K20 and last night I noticed it has tilt steering and he said I could have it. My '85 K20 does not have tilt steering and I was wondering if it is a worthwhile upgrade since there is absolutely nothing wrong with my steering now. His '84 is an auto and my '85 is a manual trans if that makes any difference. I have a steering wheel puller so I can keep my steering wheel if I do it. Should I swap the units?
