I just bought an '85 C-10 in excellent condition. It is worth spending some money on. However, there seems to be little forward-back room. Definitely seems to be less than in the '67 I had years ago. The steering wheel column seems too long and even with the seat back as far as it will go, it feels like the wheel is much too close. Obviously I could learn to live with this, but if anyone has any suggestions about getting a few more inches of room, I'd appreciate it. Somewhere I read that the seat from a "late model" Silverado uses thinner foam and can provide more room. I don't know what was considered "late model" in this context, nor whether the seats are easily interchangeable in respect to mounting holes, etc. Maybe the gain wouldn't be worth the effort and expense. Thanks in advance for advice.
