EDIT - I bought it from RideWill but it looks exactly the same as that SJS one linked above. As noted in my sale thread, it pops up in a few places.
EDIT2 - though mine has a bit more clearance I think. It takes a 45mm tyre (without mudguards) and is 400mm a2c. I reckon 40 with guards would be OK - could check that for you.
Buy mine! https://www.lfgss.com/conversations/385498
