1970 Chevelle Propeller Shaft Stripe Colors
[ 1970 ] | [ 1971 ] | [ 1972 ] | [ Intro ]
Note: Only one example of each particular model/engine/transmission is shown for each combination. If, IF there are any variations found they will be noted. It should also be noted that the TH350 {M38} was coded the same as the TH400 (M40) but noted as M40 CBC in 1970 at Atlanta so any L48 or L65 engines with M40 CBC designation are really M38 TH350 transmissions.

There appears to be a change in M20 & M21 shaft codes for L34 engines sometime between 1110 and 1114; TG seems to be used at least up until Nov 10 and DL at least as early as Nov 14. The number in parentheses are from the DATE block. | ||||

There appears to be two color choices for L34/L78 engines in sport coupes and convertibles with M20 and M21 transmissions, BL-YE & PK-OR. The BL-YE code was used until at least 10-27 but by 10-31 the code had changed to PK-OR. Anyone with an L34/L78 build sheet from KC with either M20 or M21 4-speed between the dates of 10-27 and 10-31, I'd appreciate a copy of the sheet to narrow down the dates. | ||||
