I'm looking to replace my steering wheel and want to know what other cars/trucks that I can take a wheel from, and the years.

I want a grant challenger wheel but I think 13.5 is too small for manual steering.

How small can I go without making it too hard to steer? I only drive the truck on weekends and it's pretty easy to steer already

 

A 15-inch wheel is about right even with manual steering although steering effort will still be high if ya have wide front tires and low speed. I had a puny 13-inch on my 4x4 with manual and it was a chore to steer the pig. The PO was an idiot. You need radial leverage and a 13-incher reduces that mechanical advantage.

I like Grant's 15-inch Formula GT. Nice grip and nice look. It's about $115 from Summit.
