As far as i can remember they have all ways been on our S1, but I'm starting to wonder. Does the champ and the LR have the same stud patern?

I have a nice set of those but I don't know if they are SWB or LWB ones, Is there anywhere you can get the nuts and bolts to hold the two halves together nowadays?
