Who makes whole new front ends?

heh, I love spending other people's money

if you're talking about the sheet metal as well, and you have the $, why not go Grigg's?

it's a front-steering deal with better geometry than the original. About $6k, though, but pretty much considered the ultimate in front end upgrades for the purpose of better handling for the early cars.
