For reference, BKO is bronco lover speak for Bronco. EB is Eddie Bauer (and in some circles early bronco, as in classic little bronco from the days of yore

--Begin cut and paste--
Well, I bought this '88 EB BKO about a year ago now, it has sat in my drive way the whole time I have owned it. I just picked up a '94 4x4 F-350 w/ 351W and a ZF5 for a very reasonable price and was just going to part it out and use the good parts of the front clip for a new style front clip swap.
One thing led to another and I decided to finally start on the BKO. I pulled the front clip off the BKO and found the frame to be in terrible condition, sooooo... I decided to put the BKO tub on the F-350 frame. I cut about 23"s out of the middle of the F-350 frame, spliced it back together, and added a cross member for the forward tub/bed body mounts.
The rear most tub mounts will go through the frame rail and I haven't got them done yet. The lengthened wheel base was intentional. It is stretched 6.5"s from stock BKO wheel base. The rear quarters need a lot of work anyhow, so I will move the wheel wells when I fix all of the rust.
Things still on the list to do: Install the '94 Dash and wiring. Re-plumb the fuel lines, run new brake lines, install a new tail gate, and fab up some new bumpers. The rear bumper will mount over the 4"s or so of rear frame rail that sticks out, you wont even know its there when done. After all that, then I should have it ready for paint, not sure if I am going to do it myself, or take it in to a couple of guys I know that own a body shop.
Anyhow, here are the pictures:

Here is the BKO I started with.

Here is what it looks like now, the front clip is not bolted down yet, it still needs the core support body mounts massaged... They were stuck in there pretty bad...




This one, you can just spot the frame rail splice. I intended to take more pictures of the process, however, I was working up to my buddies shop, and tight for time, so I didn't get as many pictures as I would have liked. The frame splice is a butt joint, beveled and welded, and then plated with a 3/16" thick diamond type shape on the outside, tops and bottoms.
The F-350 frame is not a perfect fit. The front two cab mounts, and the core support mounts both need about 2.5" BL so the tub clears the higher rear frame rails of the truck frame. I am going to turn some out of 3" round bar on the lathe.
The second set of cab mounts, just behind the front seats, require re-using the old BKO body mount brackets, as the pickup ones mount inboard of the frame rails through a cross member. The four mounts in the bed of the tub just require a hole saw through the frame rail on each side, but I added a 3/16" cross member to the front set for additional strength.
All in all, I am happy with the way things are coming along. I intend to sell my '99 pickup, and daily drive and tow with the BKO. I will build some custom front and rear bumpers for it, so you will not even know the front is body lifted. The pics of the truck are with no lift, that is just the difference in stock suspension height.
Later,
