03 Dakota ext cab

[Vimes]

I found the track widths on the Corvette at the sites below, but internet information is only as accurate as what gets keyed in:

https://www.edmunds.com/chevrolet/co...eatures-specs/
https://corvettestory.com/specs/2003...cs-options.php

The Dakota specs came from:
https://www.edmunds.com/dodge/dakota...eatures-specs/

I would expect that the same site providing information on two different vehicles would at least be consistent in where they're taking the measurements, but perhaps not. The wheel track is supposed to be taken at the wheel mounting surface.

The wheels I'm using (just for the build process) are a set of OE Wheels CV05 in 18x9.5, for a C5 Corvette. Thought they were 18x10s. The offset is 2.12in, backspace 7.38in.

Edit - removed old information.

The shop just called back, and we have a definitive answer now. The Corvette, as you say, measures 71 inches outside to outside on the tires. They took the same measurements and had the same read. The Dakota measures 71.5 inches (whew) outside to outside. Therefore, we'll be running with it like it is. The fenders will be quite a bit closer to the tires with the new suspension, so they will likely need some clearancing/flaring work when I get the truck back. That'll be a helluvalot easier to do than narrowing everything then trying to make all the other stuff fit.

I did briefly consider going ahead with narrowing it up and having room for the wheels (I'm a fan of the old styles) I want, but I don't want to deal with the problems that would cause over an appearance thing. It makes far more sense to keep the suspension stock and supported, and change the wheel appearance. My main thing is functionality, durability and performance, not looks. There are Corvette wheels I find acceptable, just not quite the look I wanted. I'll probably wind up with a 5 spoke mag similar to the wheels I'm using for the build.

What I really wanted, no real specs, but almost 50lbs according to US Mags:
