If the options for '96 were the same as my '98, then the push putton transfer case was an extra cost option. The floor shift (which I much prefer) came standard.
I don't think you will find an electric fan setup that will keep a Dmax cool if you tow heavy. The mechanical fan will move way more air than any electric fan setup that was available when I was looking into the conversion.
In rifles I'm kinda partial to the old Lee Enfield and M95 Mauser. The AR-15 is still the one I'd choose first though. In shotguns I like my Ithaca 51 for clay shooting and my Remington 870 for home defense.
I've got an old McCulloch 10-10 automatic that is probably out of the '70s. What it lacks in power, it makes up for with sheer noise. ;) No sissy vibration isolation handles for me.
Looks like OnStar changed their mind: http://www.foxnews.com/politics/2011/09/27/onstar-reverses-course-on-policy-change-after-schumer-raised-privacy-concerns/?test=latestnews?test=latestnews Of course they could still do the same thing secretly if they choose to.
The onstar module can be removed from most if not all GM cars if you don't want it. In some cars the module also has other functions though, like bluetooth in some Camaros
My uncle owned two Belarus tractors in that size range. He didn't have any real trouble with tham that I know of other than having to replace the clutches on both machines. Can't really go wrong for that price.
Those numbers are for the newer body style trucks. Maybe the trucks out of the '90s were different, but I can't see how the inner wheel of the dually would not hit the wheel well unless the axle mounting flange were further toward the outside of the truck.
Just did a quick search. From what I have found the SRW axle is 66" flange to flange. The dually pickup axle is 74" flange to flange. The dually cab and chassis axle matches the SRW axle at 66".
