Well I have a 76 E350 460 with a motorhome body 25ft with duallies. And I am trying to find out what the lug pattern size is ? Dually wheels from from what year to what year will fit. I know my 99 F350 won't they are 8+170mm and hub centered rims. Not bud wheels. If anyone here has a clue please let me know. Thanks

 

They are standard 8x6.5 1973-2011 will fit them just fine! Only the trucks went to metric the E series still has 8x6.5 and dana axles.

 

Thanks for the heads up I have a brand new set of Alcoa Classics 16' 8+6.5 dually wheels that I wanted to put on my stupid pick up with 8+170mm. And I was hoping they would fit my motorhome. The motorhome had steel wheels. Now I just need the $ for tires.
