Cheers Franco, here's what they asked for...
"Best format is either eps- or pdf to size (we could open and use the pdf you sent- but need it resized)"
I believe it was done in InDesign previously, those files should be in the .zip if that helps. There's a couple of minor changes to the PDF in the .zip file that need to be added also.
Many thanks,
Simon
PS. Cheers solidteezme, it's an Australian Lowboy cab, it's the one I'm trying to sort out some CNC plans for.
