In all my time here I've never heard of anyone doing a front end replacement. That's a huge project, and definitely requires skill to make sure you end up with a car that is both safe and drives normally.

This is a suggestion (b/c I have done it), but could you just transfer all mechanicals to the better frame? I've basically done that with my RS, the engine/trans/interior/miscellaneous exterior parts have all come from other cars. The RS had the best chassis of any eclipse I've bought, so it became the recipient of parts instead of the donor.
