Well, I am ready to race this friday!
Your picture of the Lincoln is basicly what mine looks like but I guess I would call it a Miller Lock because that is what I used.

After installing the diff which is identical in width (but is a bit beefy'r), I had to install the old springs from my B210 which luckily I stll had. Misplaced the U-Bolt brackets but ended up making a new pair.
The rear mount for the leaf springs had to be swiveled back to accomidate the longer springs. After they were installed, I drove and noticed a clunck noise in the back end. What had happened was that the rear bracket swiveled back to far and dropped the car onto the springs. Good thing that the car was still high enough to not hit the tires.
So, I reset the springs and rear bracket where I wanted it and then welded a stop bracket at the rear end so now the springs are set. Flex on the springs but no flex back on the rear bracket so better traction at the line on takeoff. The ride seems no different other than a slight shimmy around corners.
I also ended up rejetting my carbs and constructed a fuel cooler can. Just install dry ice and away I go. I am looking at moving up into the next faster bracket at the drags this friday.
Filled the NOS bottle the other day so I won't be running out this time although I still took first last race.
Hope to see DD there with his Ute.
