35 lbs on a street car is nothing.
Agreed on this point 100%.
Only way you'd need to ream the spindle is if you wanted to run large ball joint UCA's (73-76) with a small ball joint spindle. But if you're swapping on '73+ disks you don't have a small ball joint spindle, and since the car is a 5x4" stock pattern it doesn't have large ball joint UCA's.
This is what I was talking about. I run large ball joint UCA's, the RMS ones with a drum spindle. Which works with a willwood setup. .
