"Different truck altoegether!!! This truck is ext. cab and the previous was a reg cab. and this truck has tow/haul mirrors."
Ok Singlestylin simplton - yes you are right, but if you look at all the pictures in the series you will notice that all are 8-lug wheels(which is a good indacator of the HD or NON-HD status) . In pix 1 and 2 you can see the IFS very clearly.

If you look at pix 3 and 4 we definatly see a regular cab pickup, but in #4 we can also see what appears to be a torsion bar(look closely).

And in pic 5 you see it as a regular cab, but by looking at the front end, you can also see the IFS and front u-joint. Which is what my previous post and point was.
