I have been driving my Willys this summer it has worked really well except for some heat problems. But when I replaced the 14" PermaCool fan with a 16" Spal the heat problems where gone, this fan moves air! Have started with the interior, the kickpanels are done and I am waiting for the vinyl for the trunk.
Tip o' the hat to you sir! A fine, fine ride! From America to Argentina to Sweden to The HAMB - quite a journey!!!
And I apologize. I clicked on the wrong post to make my comment. It's a beautiful car too, but this thread is about yours, which I think is outstanding.
If you don't like the wrinkles by the back window I THINK you can get rid of them with a heater like a hairdryer. I read some posts on the HAMB about it and I'm sure there are some online somewhere that may help you out. BUT it really doesn't look all that bad.
The carpet is there and the door sills. The lower door seals are Ford 38-39 I have no idea how it is done on a stock Willys.
