G'day matey, like has been mentioned above i would not worry just do what you want to do like i do build what you like how you like it as your the one that will be sleeping in it.
My 24 volter had a new combat chassis put under it after an accident i have fitted different tanks that are now side fill due to the smell of fuel after a fill up the door tops are from a burnt out 110 and the bulkhead was all i had[series3] that did not need welding because unfortunately i have to rely on others for that due to my eye's etc.
My braking system is off a later model series because that's what i had new so i fitted it and i also have a 12 volt alternator driven off the crank for the camping side of things the sides have small windows like the carawagons sort of but not the same and slide open.
I did however question the chassis but when i went to Lichfield to view my 2a ambulance the new combat chassis's were stacked really high ready for use when needed it also turns out after after a visit from the owner of the company that makes series 2 chassis and advertises in the club mag that my series 2 ambulance has been fitter with a combat series 3 chassis again after an accident and i know this because i have the full service history so you can't always go by what you see at first glance

.
I tax my motor on my dissability form so thats the reason i am not bothered what it is made up of regards models tax except or not in a way i am lucky to run what i like but of course it does have it's down falls
