Brian....I see that seller also had another 'burb for sale.
It looks like he has 'converted' it to a clamshell model.
Spot the
hinge holes in the rear corners. Or did they
all come with them,with blanking plugs?
IMO your new purchase is a more honest original,and as Giladad mentions,take all the parts hunting costs in time and fuel into account and you've got your self a winner!
Good luck with your new project.
