No they vary a bit by size, 3E and 3EE is a bit different, they might fit but not so well. U can probably use some other cars header but still it would not fit well, you will run into problems liek backfire and such, headers are tuned for exact firing order and such dont ask how who knows!
U can find some headers on Car-part.com, they should be preaty cheap, call em up, make sure its same header u need, and have them ship it, i had a few parts shiped, most places ship same day, you recieve next day! junkyards are awesome, u can also find something local!
