Where will these Boyds sit when my truck is assembled??

[1971gmcshortbed]

Hi 6772, Since my build is semi-budget, I will be using my old Boyds. I pulled them from storage and dismounted 1 today at work, acid cleaned it and polished it. It looks alot better than when I started.

Anyways I originally had them on a 98 Tahoe with a 3-4 drop, they sat nice. They are 18X8 or 9 (not sure). The tires are 285/50 18. I believe the backspacing is 5 or 5.5. My question is with the bed on and front end put together, will it sit ok? Again, I wish I had real numbers however I am working off of memory, I know the spindles are Bell Tech 3120's (3") and a 1 inch cpp spring. I believe I have a 4" cpp leaf with a 1.5 ece shackle. So Will I sit ok?
I don't mind sitting inset as long as it's not too much to where it looks funny.
Any comments/suggestions are apreciated, especially pics. Please excuse my mess, full time job.. Thank you 6772.

Those wheels cleaned up nice. Do us a favor and measure your backspace. With out that it's going to be hard to give an accurate answer.

I brought another one to work today. They are 18X8 with 5" backspacing. Thank you 6772.
