Bagged 78 K5 with 22x10 outback?

[biggerpickle]

Hey guys, I'm bagging a 1978 K5 2wd, and was wondering what the correct offset for the rear wheels would need to be if I were to get a 22x10 out back without hitting the bedsides.
Thank you!

Are you trying to lay frame or just get low?

A member by the name of 67cheby just finished up his blazer and I had to do some searching but he's running a 22x10 with 4.5 backspacing and it's tucking.

Here's a link to his picture I know it's not the greatest due to the door being opening but you can tell it's not touching the bedsides.
