thanks for any info.
Exh manifold ....042 is RH for '65 w/250HP (all) & 300HP w/pwrglide. Also for all '66 + '67 327 engines & trans w/out K19 A.I.R. system.
Your AFB numbers are not sufficiently descriptive.
3720SA was used on '64 + '65 300HP/w pwr glide. (Kind of matches your 042 exh manifold). B4 on a triangular metal tag could mean Feb '64.
3721SB was used on '64 300HP/w manual trans. Not sure what MO stands for. "I" was not used, so maybe it's Dec, '70 service replacement?
