Love how you did your cross member... may be stealing that for mine. Go Klingons!!!!!
Its a latch from a new Poison Spyder tire carrier. Not available to the public but I bugged Larry McRea (owner) enough that he sold me one.
Its basically a universal door latch for a hot rod (bear claw and pin) and PS made the mounts.

Now that i know what I am googling I can build my own. I may have been offered the same thing as you but at this point I respect their proprietary aspect and will try something either similar or go a way different route based on something I turned up in the dumpster here in Germany. 
thats exactly what I got from them (just not the spindle and bearings, got those from Comp 4x4)
I actually bought my own bear claw latches off of ebay and was going to make my own latch setup, but I'm getting tired of spending hours building stuff that if relatively cheap to buy. I value my time as much as my money, if i spend 5 hours to make something that costs $100, I didnt save anything.
I still have to modify the PS latch housing to work on my bumper. Nothing is ever bolt on on my Jeep, even if its supposed to be bolt on.

I got it from Summit. Part # CU-58202-01 $433 http://www.summitracing.com/parts/GRI-CU-58202-01
Its a combo kit that includes a fan and aluminum shroud. The fan that comes with the kit is VERY thick. There is no way it would work in a Jeep with a 4.2L or 4.0L. It actually didnt work with my set up. I had to get a different fan but thats because I cheated the drivetrain ahead a couple inches so I wouldnt have to get new driveshafts made.
Sorry to keep flogging the proverbial deceased equine... Do you have pics or a model/link to the BC latch you ordered before the PS kit? I was looking at the junkyard today at different styles and not really sure what I need to be looking for.![]()
