I have a 1997 Smilie LWB and curious to know what the stand diff ratio would be.
Is it marked on the diff?
Can the ratio be altered and if so what would be the best ratio for highway economy?
It is currently being converted into a campervan.
Is fitted with a 3.8litre Buick V6 and is auto.
I am not interested in breaking any speed records but would like to sit under the 100/110 kilometres speed limits ((90-95 is good) and get good fuel economy without taking off from the lights like a 10 ton tractor.
