Thanks Paul! I think they would since the Marrad seat has higher leg/side bolsters.
They definitely tighten the chassis up but egress is definitely 'tighter' too. I thought I would like a cage but as long as Warbird is my daily that won't happen.
Without measuring I can't say for sure, currently at work, but i think it is pretty close. You can adjust the seat left/right via the side mount/slider bolts but it will limit seat travel due to the seat hitting the tras tunnel or door bars. I can't adjust it one way or another w/o limiting seat travel to the point my wife couldn't adequately reach the peddles. Overall dimensions of the seat? Here they are:
