The issue with the old CVDs being too short was easily fixed, I just added about 1/8" to the hole centers. I made the dogbone pin a bit longer too. The inside bore is full length, and I turned the wall down to about .045, so they are lighter than they look. And I am pretty sure it is grade 8 material, which should give excellent wear characteristics. I plan to paint them flat black and heatshrink over the paint, they look nice but I'm sure rust is nobody's idea of bling
