To clarify the point, a small hoop extension to a rollbar is now not allowed under MSA or FIA regs (where fitted they have had to be removed) - some details of the discussion prior to this year's meetings can be found at
http://www.mogsport.net/info/rollbars.html - so the seat has to be lowered to get the required clearance. It is unclear whether a full width bolt-on extension may be allowed - may simply depend on the scrutineer on the day...
Thanks for the help Chris. Can one lower a stock Morgan seat that much?
Thanks, I'll try Mogsport - but what I'm looking for is a stainless bar for road only, I have no interest in track use.
Road Morgans do not roll. However, if you want one, it is best to get something that will protect you so it must be higher than your head. As your top will prevent you using a roll bar that high, your solution, as Chris notes, is to lower your seat.
