Kach22i: agreed - a flatbed blank slate would be an ideal starting point. More work though?

Yeti: Brighton - cool! Maybe one day I can see your project.

Do you have access to junkyard diffs too? Might be worth trying the tallest.

Just FYI, I stuck the tallest possible final drive in my 1.0L Firefly out of about 5 options.

It's fine for mostly highway use in a non-loaded vehicle, but is a bit harder on the clutch starting on hills and in stop & go urban use. It essentially made the "new" 1st gear equivalent to halfway between the original 1st & 2nd, if you know what I mean. More clutch slippage to get the car moving. All that got me about 5% better highway MPG.

A better solution would have been a taller 5th, but there were no OEM swaps for doing that.
