Here is a shot of my adapters:
Here was the first problem I ran into. The winch gussets on the inside of the bumper were hitting the front crossmember so they had to be trimed.
Next problem was the top of the bumper was too wide and was hitting the core support so it also got trimmed.
After that it was just drilling some holes in the frame rails and making some mounting plates to fit inside the adapter. Wouldn't be such a huge deal except my welder is on its last leg and would only weld short burst at a time which took forever.
Each mounting plate is indexed inside the adapter using 2 rivets. From there I fabed some temporary mounts for the turn signals using some 18 gauge sheet metal so I can get back on the road. They will be replaced once I have the filler panels under them fabed.
I got lucky with this bumper. It was exactly the correct length to fit inside the fender flares and the lower "skid plate" was the correct length and angle to be mounted on the radiator core support under the Jeep.
This was a cheap china bumper off of ebay. They welds are chunky and is painted rather than powercoated but for $280 shipped it seems to be a fair deal. I have about $380 in this set up as it sits but will probably be a little over $400 once the I finish the filler panels.
If I had to do it again I would advise people to have the bumper they plan to use there when they make the adapters that way you can be sure you like the exact placement. I'd like to be a 1/4 in higher as fitment was very tight at the top of the crossmember.
