Backspacing ?sssss

Im tryin to lay frame on 24's what kind of backspacing do i need prolly runnin 10 wide

if you dont want to narrow your rear end you need 7.5" backspacing for a 10" wide wheel

how can you give an answer to this question without knowing what kind of truck?

becouse on his profile he has a 2003 fullsize gmc

I have 24x10 with 7.5" backspacing and i narrowed my rear 5" so they would fit with the bodydrop

i know i need to narrow rear end i plan on it and i know i need bad habits control arms, was it 5" overall or 5 on each side, and can u hit sides or are ure wheels close to frame
