I have a 1935 Model PJ Plymouth which has a rear end gear ratio of 4.125 to 1. Would it be possible to replace my gears with later model Plymouth gears that could give me a higher ratio?

According to the Hollander Parts Interchange Manual, the 1935 and 1936 Plymouth rear axle gears are interchangeable and a higher ratio of 3.7 to 1 was available for both years. The part number for the gear set is 638848. However, you probably will lose some performance.
