hey guys, i have a new set of 1920 radius rods to go in my T and I was told that before i install them to measure the old set that is still installed and then match those measurements when adjusting the nuts on the end of the radius rods nearest the engine. I measured mine and there is an 1/8th difference! does this surprise anyone?? should i just make them equal?

I assume you're talking about the rear radius rods. The variation isn't surprising. More important than the length of individual rods is the squareness of the entire assembly.
