I have a couple of questions for the ignition lock experts.
The type of locks that I have questions on started with the column style lock beginning in 1970.
I have attached a picture of some locks.
Lock #1 is from a 1970 Sport Satellite with the non Rally dash and has a satin finish that is similar to the dash switches.
My first question is - were the satin finish locks used after 1970 and if yes till what year?
Lock #2 is from a 1970 GTX with the rally dash and has a shiny chrome finish.
Lock #3 is unknown and also has a shiny finish but no thumb tab on the knob.
My second question is - what year did they remove the thumb tab as shown on lock #3 ?
Thanks! MJ
