I have an 86 and I put a smaller wheel in. I went out and measured mine. Steering Wheel to the back of the seat back, was 15". If the tilt is all the way up, there is 8" from the bottom of the wheel to the seat. And then less if the wheel is tilted down.

I know swapping the steering wheels did allow for more room for the driver. I'm not big, but I didn't like the big original steering wheel. I always did feel, that if you were a big person, it would definitely crowd your body. I felt crowded by it, but I got SPACE issues.

And another thing, the seat does make a difference. I had a 90"s style seat when I bought the truck and then went with correct bench for the 80"s. The 90's seat, I felt did sit down and further back.
