I was surfing another forum and found this link. It shows how to do certain things like painting valve covers, installing springs, hood pins, underdrive pullies, etc. There are also some pretty cool DIY mods that might be helpful.

This link is only for S197's, although Mustangs from all years might be able to get ideas from it.

Cool stuff, moved to reference.

 

My 2008 gt bullitt sits on 18x9 (F) and 18X10 (R) with the stock rubbers in the front (235/50Z18) with Nittros out back. I was thinking about dropping her an inch or two. Do you know how LOW she can go before rubbing? I was looking at the proline droppers! Whatcha think?
