CRACKED '97 MANIFOLD

[FRANK STAGNITTO]

GOOD AFTERNOON, I LEARNED THAT THE '97 INTAKE MANIFOLDS ARE "PLASTIC". ...SO I HAVE A CRACKED MANIFOLD!

I HAVE LEARNED THE SAME MANIFOLD WILL INTER CHANGE: AURORA '95-99, DEVILLE '95 [8-279 4.6L],
DEVILLE '96-'98 [8-279 4.6L], ELDO '95-99, & SEVILLE '95-'99.

WHAT I DON'T KNOW IS WHICH OF THE MODEL YEARS USED PLASTIC MANIFOLDS?

IF ANY OF THOSE YEARS USED METAL MANIFOLDS, WOULD I BE CORRECT AND WOULD I'D DO BETTER....UNDERSTANDING THE INTER-CHANGE THOUGHT..... TO FIND A METAL MANIFOLD TO REPLACE MY CRACKED PLASTIC MANIFOLD? 

IF THIS AXIOM BE CORRECT, AND I SECURE A METAL INTAKE  MANIFOLD, I SHOUDL BE SURE I GET A CORRECT INTAKE MANIFOLD GASKET, ONE DESIGNED FOR METAL TO METAL OVER METAL TO PLASTIC.

YOUR THOUGHTS ARE GREATLY APPRECIATED BY ME AS WELL AS MY WIFE....HER '97!

I dont know about the Northstars specifically but on other GM motors the change to plastic was not just material it was a different design so they were not a direct swap.
