I'm going to need to replace my ring and pinion and as most know the options are limited..
I've got a 4 speed tranny and was wondering what is a good gear ratio so it can cruise fairly well..

Looking at a 3.55:1 and a 3.90:1

what are pros and cons or options.

Thanks for any help to this backyard mechanic
