Many Volvo 122's have been converted to the overdrive transmission. While it is great having the quieter cruising, having the proper switch to activate the overdrive is something else. If you'd like your conversion to be period correct and convienent to use, we got the goods.
The steering column surround in all manual transmission equipped 122's have a reinforced boss that can be drilled to accept this Volvo 123GT replica switch that mounts opposite the turn signal stalk. (Once you look inside, you'll see that it's really very easy to properly drill it out). Glue-on handle is also available, as well as the Lucas 4th gear lock-out switch.
