Got the 58 Apache close to road ready. Running a 350 and a 2004r, B&M kit to shift off of pressure. Looks like I have a 2:73 rearend from a 73 firebird, if I remember orrectly. What would be a range of acceptable gears to replace the 2:73s? Will be running 235 or 255/15s. I'm thinking 3:42 or maybe a 3:73 ( TA or Z/28?). What would be good cars for a swap-I could do an entire rear end by myself, have never done a ring and pinion. Thanks.
