Also remember that almost anything is possible, it just depends on how much work you're willing to do and learn. Along with the 63 panel i'm building i'm also helping my nephew build a 60 step. it was all orig but in bad shape. We already put a 78 tilt column in (took a couple of hours but was easy), we only had to change the column bracket, we were able to leave the column the length and even the shaft matched right up. we also put in the power brake booster from 78 and it also only took about an hour.
