Yes. They can absolute buggers to fit. I know some have sent them back to Strapcode. It's a bit of a trade-off because you want the endlinks to be snug against the case.
I think that passing a fine thread round the end of the springbar to then pull it towards the lug hole sometimes works.
Either way, they're fiddly buggers and when you've struggled for ½ an hour you're not so inclined to do lots of strap changes.
