I'm 99.99% sure, that since I have an EARLY C36 engine with a serial number below F159969, that I am suppose to use the 202.540.40.32 pn# (cheaper!) even though I have option code# 957 in my DataCard.

FWIW, HWA 202 540 03 32 is for engine sn# starting at F159970 and up to the end of MY95 with OPTION code 957.

Am I missing something ?
