Brian sent me an update on his adaptation of a wranger swinging assembly into his CJ-3B.
“I was going to use a dual master cylinder kit, but instead I located a set of swing pedals from a early Wrangler. With the extra 4 inches of cowl height in the CJ-3B, I found they would fit. This provided me two advantages: (1) the assembly came with a brake booster and (2) I can use the hydraulic clutch kit from Novak to simplify life the install.
Here’s stock assembly from a early Wrangler.
