They are different. I believe the OEM part numbers are:

Left: 3W3Z-9431-BA
Right: 3W3Z-9430-AA

Many owners have upgraded to headers. This may be an option to consider if you are only considering new parts.

Did one crack? Manifolds are hard to break.

Typically the 03 cobra ones are fairly cheap....

Can you get those new?

[NorthShoreChiMM]

no, none are cracked but doing a rebuild in the spring and want to start gathering hard to find parts. Mine are rusty, looks like they came out of the deep sea.

Clean up and Powder Coat.

[Mr. Man]

Clean up and Powder Coat.Will powder coating take that kind of heat? I don't know. Might want to clean them up and Jet coat them.:)

[NorthShoreChiMM]

would sand blasting them take care of it and just "jet coat' as said above take care of it?

If you get them coated, they will Sand blast them
