Nope, It has already been proven times over that a solid mounted rack with a straight axle doesn't work right. Even the least deflection is going to change toe in. A lot of guys screwed their cars up back 30/40 years ago trying it.

48 Chev 3100 that will run a 292 Six.

77 C 30 dualie, 454, 4 speed with a 10 foot flatbed and hoist. It does the heavy work and hauls the projects around.
