I thought about putting a tilt/telescopic column in my 1964 Polara. I found that anything Ididit or Flaming River had was too short. I had also installed an early '70's cruise control on my '64 column, and figured I would lose that, going to an aftermarket tilt column. I also thought about C-body columns. To get one without a column shifter on it, the donor car would have to be a console car; kinda rare. Then, the telescope feature uses a unique steering wheel, with a lever on it to engage the telescope feature. I ended up just using my stock column.
My biggest concern was getting a comfortable distance between me and the steering wheel, since I am a bigger guy. I bought a set of seat extenders from Jeg's and a smaller 14" wheel from Classic Industries.
