Seat latches for buckets out of a 4 door

I've seen a few of those 4 door buckets. It sure would be nice to be able to use them in a 2 door. I've also seen some work vans that had the fixed buckets in them.

I have 1.5 extra sets if someone has a set of seats they need to make work. You would still need the spring, but that seems a lot easier to find (the latch seems to be A-Body specific, don't know if the spring is yet). Time will tell.
