I have a 1938 1.5 ton and need higher gearing for better top speed. Right now runs about 38mph but way to much rpm for my liking. What are my options?

Taller tires currently 6.5x 20 which I believe are roughly 34" tall, so maybe 8.25x20 which are 38" tall?

Higher ring and pinion gearing if anyone makes one or has one, my rear axle does not have a tag on it?

Overdrive unit gear vendors has one but its costly 3300 for parts plus machining work and my time to install (free)?

Different transmissions or secondary trans, not sure if this is an option?

Any ideas or help is greatly appreciated.
