3.54 rear gear in 46 to 48 convertible

[bobH]

For whatever it's worth, wife & I have a 46-48 convert (47F), and it came with 3.54's. In my opinion, it's a slug to drive, sluggish off the line, won't keep up on freeway on-ramps. Once going, it's ok. And, at freeway speed, it sounds 'busy', and I would like a taller gear. So, this is a 'non-answer'. I'd like taller highway gears, and lower stop-sign gears. IE, I'd like 3.78's and an overdrive. Or, maybe just a T-5 or similar. JMO
