Griffon Spitfire Mounts

I’ve been posed a question which is beyond my knowledge (what isn’t!). Now, are the engine bearers from the Seafire 15 and 17 (so early Griffon) the same as those used on the Griffon Spits with the Griffon 65 etc.

That asked, they’re British, so they’re bound to be different even if they didn’t need to be.

Anyone any ideas?

Thanks,

G
