centre caps for 15" P slots

Does anyone know if the mk2 14" p slot caps will also fit on the rarer 15" p slots? 
Thanks 

One time I had both in storage. I reckon they were the same but not 100% sure

think I've got some blank ones if you need some

Thanks Ian, I was actually selling a set on eBay and someone had asked the question. I've Sold them now but kept the other set with the Pirelli embossed logo. No doubt they'll sit in the garage for another 20years collecting dust.
