There are some universal ones for sale on ebay at the moment not sure where they are located though. Took me quite a while to find these locally for the countryman. The lock onto the gutter and clamp down so no holes to drill. Not sure if there where any specific bmc racks. A couple of Perth facebook groups you could ask in.
Other unusual accessories I have is a little picnic table that attaches to inside of the door, portable period picnic radio and nice matching NOS 60's picnic set and 60's surfboard as seen above.
