E120 Classic trunnion questions

Hello. I recently purchased a boat with two E120 Classics flush mounted in the pilothouse. I would like to move them to the flybridge but there is no room to flush mount them there so they would have to mounted via trunnions. Unfortunately I don't have the trunnions so my questions are as follows:

Are trunnions for these available from Raymarine..?

If not, I'll know I'll have to try to find them online (ebay or something). I've already seen one but it was the trunnion part number for a C120 classic. They had it advertised as fitting both the C120 & E120 classic units. Can you tell me if that C120 Classic trunnion would work with a E120 Classic unit..?

Last, do you know if any of the new model trunnions will or could work with the E120 Classic with perhaps some minor modification...?

Thanks, Adam.
