I don't think the lug pattern is different between SRW and DRW with 8x170mm. I don't have a clue about the backspacing.

2005 and newer the lug pattern is 8 on 200mm I believe - I know it is larger than 99-04 - the 450/550 went to 10 lug pattern in 05 also

Check your source again mizzitch on the 2005 info, I got a set of Weld's in the garage that I test fit this past weekend. 450s and 550s run larger big rig style wheels that are 19.5" diameter due to the GVWR they can load.

My '06 F-250 is still 8 x 170. My backspacing is 6". I don't know on yours being it's a dually though.

Yeah all the dually trucks changed lug pattern. Not the SRW trucks.

I stand corrected. I found the Body Builders document that shows the 8x200mm.

I think you're right, maybe a 220mm.

mizzitch is right. the 2004 F-550 out in the driveway is 8 lug, by 225 mm. 8.885" center of lug to center of lug, * 25.4= 225.6

i will be able to tell you the bolt pattern of the 2005 and up (particularly 2007) in a few days.
