I never noticed a track width difference on the 2wd's?
As I understand it, on the 4x4's it is different to help with traction; the front wheels and the back wheels are in different tracks. I never really understood why though?

You can have your wheels widened but I think it might be easier to just buy them already done. I think Stockton Wheel or Wheel Vintique (SP?) have 10" rims as a stocked item.

The Blazer should turn better than the truck, even a swb. If there is a HUGE difference you might have a problem on the truck that you just didn't realize until now?
I just bought an '87 crewcab. When I went to pick it up from some service work the owner told me the pitman arm was on backwards. I had noticed the wheel was pretty far off but didn't really care as I am going to put 1/2 ton suspension under it. He found it hard to believe that I didn't notice it only turned about 3/4 of the way in one direction? Its a crewcab, it's supposed to have a bad turning radius...
