well, for me a truck rear end would be taking the hard road. Have to have it shortened (axles and housing), perches moved. I'll get a complete 8.75 B-body.
Like I said fits y'alls needs...
I wasn't sure that the eight and three-quarter you had was just the perches. And of course jab isn't specific about why he wants to replace the 9 1/4? In what?
