69 cutlass swaping gears in my rear
so i have a 69 cutty it has i think .... ? a 8.5 "O" 12 bolt cover but 10 bolt gear plate ?
ITS coded R2 wich is 2.56 ratio wich really sucks cause im going for a street strip ( probly go to the strip just a couple off times ) but its just more for crusin around burnin the tires and tryin to get the front to lift up when i take off
What is the best / not to expensive ways what will it cost to go to 3.42 or even a little taller/ shorter ( herd it explained both ways ) 4.11 seems to be fore drag racing only and would not be good for cruising it will have a mildly buit 350 in it and posi would be nice but that all depends on cost also
has any one swaped out there 2.56 rear for somthing else please share thanks

i was just reading up on this via nova and chevell threads and i went to go check my other cutlass the supreme is canadian built and from what i am reading it may verry well have a chevy 12 bolt in it from factory ?????my cutlass s is amarican built and is in way beter shape and plan to spend more monney time into this one
the rear end looks physically diffrent it is a 12 bolt and i can not find any code letters like on my 2.56 12 bolt O diff
were all canadian built cutlass's equiped with a chevy rear end ??
