yes the back ones are Spinlock. I just gave up trying to source new cams and pulled them off and replaced them. I went down a size as ropes have got better and we dont need the diameter that we did 15 years ago.
mauri pro sailing in US has cams and rebuild kits in stock.
You can also get cams to suit smaller diameter to help prevent slipping.
I did mine last year, and came with the new shells also.
$40 Good as new.
