Well i was having a debate with my know it all retired from GM step mom and she swears that while working at Pontiac Assembly she roll tested 442's i know she may have roll tested grand nationals and Monte's but i thought ALL 442's (and cutlass's in general for that matter), from that era were unique to Lansing, am i right??

 

I think she may be right. Henry

 

Doesn't your Chassis Service Manual show the assembly plants for the models?

 

Cars and Parts Catalog of Oldsmobile 442, W-Machines and Hurst Olds ID Numbers 1964-91

Shows 86 and 87 Cutlass assembly plants as:

Pontiac, Mi. code P
Arlington, Tx. code R

DAMN looks like she may have one up on me! grrrrr, haha well at least i was right as far as the hurst/olds went i know all those were from lansing

 

'85 442 was for sure available from Arlington, heck they may have made all the white ones!
