It appears the track witdth on the E350 is around 67 inches and my truck is around 63 inches. Does anyone have experience with this rear end in a similar truck?

Joined: May 2005 Posts: 8,878 | Well, your measurements tell you it probably won't place the original wheels under the fenders where they fit... Are wheels available with the necessary 2" different back spacing? Are you OK with using different wheels front and rear? Another option is a GM 14 bolt rear axle, they come about 63" wide in some applications. https://www.stovebolt.com/ubbthreads/ubbthreads.php?ubb=showflat&Number=686209&page=1Grigg | | | | | Joined: Dec 2010 Posts: 16 New Guy | | New Guy Joined: Dec 2010 Posts: 16 | Thanks for the tip. I am going to the junk yard today to measure an E350 just to make sure. I would like to stay with the 8 lug 6.5 inch bolt pattern if possible.

They say money can't buy happiness. It can buy old Chevy trucks though.

That one will work just fine.

Check Dodge 3/4 and one ton vans with full floating Dana 60's.
They are usually about 65" wide at the wheel mounting surface.
