Thanks Chris, I should have said any of the Stratos variants from the various manufacturers, does not need to be a Lister Bell as I am more concerned about interior space/seating positions and all are mostly similar as far a rollcage/interior space goes as far as I can see. I intend to use the car for tarmac rallying and will need to add additional bars to roll cage etc to get a log book and this would help on positioning etc of bars prior to build/painting of spaceframe. I know they will be all slightly different but have already viewed the main types but all have been in early stages of build so to sit in a completed car would help and it does not need to be a car that was built for rallying.
