OK, have a 71 with stock 2.73-non-posi I believe. Want to upgrade to 3.42 or maybe 3.55.
Upgraded with top end-kit & now want to turn it up a notch with the gear change.
Nothing crazy just want a good balance for street/highway cruising, without a huge budget.
Local transmission joint says it does this type of work.
So,is it simply a matter of changing the carrier from a 2 - 3 series along with the gears themselves ,or is there more to it than that ?
All advice is much appreciated !
