All right I'll just comment one last time

...I agree with 442w30...my 71 Lemans Sport had the T41 option...the hood on it was RA, but there was no pan, just a regular old air cleaner..all cosmetic...Olds didn't offer just the W25 hood...as far as I know, it always was functional OAI with the OAI air cleaner....and I cant even say for sure if it was even offered on anything but the "A" bodies....this is like the W35 option on convertibles..it wasn't available, but there are a number of people who swear it was, and their car came that way...not sure if you were joking, but 64 was the only year a 4 door 4-4-2 was available otherwise its..
4-4bbl Carb
4-4spd trans (or 400/455 ci depending on year)
2-Dual Exhaust
so yes, it **could** just be a Cutlass wagon with OAI...
no more....really...I promise
