Good and bad news. Seats seem good, but they are too wide at the top. I need to have a proper play with them as i just plonked them in the chassis to see if they'd fit straight in. They didn't but positioning them VERY upright does make it a bit better...
The suppliers were kind enough to answer some novice questions from me, the bad news is that their answer to "can I just trim the edge off the seat to make it fit" was a "we wouldn't advise it because that's where the strength is.."
Hopefully i'll be able to shuffle them about a bit to get them to go in...
