I'm planning on using some of the money I get back on my tax return on my LS's performance. So I’ve been researching the 3.58 gear swap in the search function. One conclusion that was made is that I should go NEW 3.58 gears. Now here’s my question. I get the whole first production run LS’s had 3.58 (2-99 - 6-99 early 2000 LS's have the 3.58) and that 2003+ V8's have the 3.58 and also 2002+ T-birds have the 3.58 (Axle tag number: 556B - 3.58). I’ve seen some of you have used the 02 T-bird pumpkin with the 3.58 gears but what parts did you replace? Is replacing the ring and pinion gear a must? Please help, this is some that I’m really looking forward to having done and I want as much feed back as possible.
