Morris Minor Owners Club

I’ve done a site search and maybe Im not using the correct terminology. My pickup bed, box, tilt? Has been lined with varnished oak. It looks nice but maybe not very practical. It needs protection from the elements. I have the canvas camper cover from my previous truck but this one does not have the tie downs on the sides or the wood strip on the roof and I really don’t want to drill holes in the roof to fit one. What I would like is a removable low profile cover that stretches over the bed. I imagine some sort of bows would be required for support and snaps or hooks to hold it down.
Is such a thing available commercially or are there drawings, photos available, or anyone with experience fabricating such a thing?
Thanks,
Bill B.
