I have an early 52 crestline Victoria and everything I can find indicates 1949 to 1953 + used the spark control valve. I have a 3 speed overdrive and a loadamatic distributor which requires a spark control valve. ?
The OP might be referring to the vacuum control canister on the distributor. If that is the case, yes, all distributors from '49 to '53 used them.
