DON'T GIVE UP!!!
Don't do it.
Just be patient and stick to your build. You've got the dream setup and now you just need to bolt it all together. I know it takes time, I've been nursing my build for 16-ish years... it's gone through 4 revisions and it's still changing everyday. You Will Make It!
Anything I can do to help you stay on target, you let me know.
and now, dance monkey dance....
also, talk to me about that 'race prep' 901 you pimped on the porsche thread. What's the story with it, what parts does it have and are there alu-plates for side cover or intermediate plate?
