mate, dont worry about it, yours isnt looking that bad.
ok so its a fair amount of work but:
its a huge relief when its all done
yours doesnt need that much work
its so much easier when the car is fully stripped.
and luckily it doesnt look anything like this:
as you can see there is a general lack of crossmember, various deficiencies in wheel arch and a serious case of repeat boot floor AIDS.
BUT it wasnt long before this
then a test fit like this
then some panels like this
then some paint like this
a new floor like this
and a very happy moment like this
go forth and weld!
