Re: 33 Bodywork
If you find a repair section let me know as mine has done the same. I did see some time ago that they were available in Finland.
The muck gets between the shell and the 'cup shaped' pressing behind, they're only spot weled together, and then there's not a lot you can do.
If I can get hold of one I'll have it seam welded or brazed to prevent it happening again. After nearly 12 years of ownership I still enjoy driving it, especially in the summer, with the windows open and going into/out of a tunnel. If you have a 33 you'll know what I mean.
