I've decided to rebuild my 1970 LC. This was my second ever car which I've had since I was 19, and it has a lot of sentimental value.
I don't want to rebuild it as a show car or a tyre shredder. I'm hoping to use the current running gear and fix up the rust and get a half decent paint job and drive it as it was built to be driven.
I've recently moved it undercover after being in the weather for about 6 years with the intention of bringing it back to life but I'm finding there may be a few problems with the body. She is straight as they come with no dents except a couple on the rear beaver panel, but I'll need to replace some bits that are pretty badly rusted.
These include;
Both Sills
Front Beaver Panel (is that what its called?)
One rear 1/4 panel
The front quarters both need a tidy up at the bottom
Both front floorpans
Rear wheel arches
All of that I can handle, but unfortunately my gutters have filled up with leaves and there is rust in both of the back pillars. See Pics.
My question is, can this be fixed and how easily/cheaply?
And in your opinion, is it worth rebuilding this car or looking for another body that isn't full of rust?
I know some of you will say get a 2 door, but its hard to find one since everyone is hell bent on whacking v8's in them and/or wrapping them around something.

Wheel Arch

Front Beaver panel (if thats what its called)

Hole in the left hand rear door pillar - Is this a showstopper???

Drivers floorpan - At least I can see the chassis rail is in good nick as is the speedo cable which I replaced when I bought the car.
Your thoughts are most welcome. Thanks guys.
I have always wanted to build a car but never have, so this is where I'm starting. Most of the cutting/welding etc would have to be done by someone else and I have limited funds, so any hints, tips or ideas would be most welcome.
Thanks
