Hi all,
I have a question about diff gears in an IRS diff, i have a 3.46:1 LSD in my commodore, i have sitting around a 3.08:1 single spinner, i have ordered a spool for the single spinner for the easternats, what im wondering is, i want to use my 3.46 gears with the spool.

Can i bolt my crownwheel onto the 3.08 center, or are the bolt patterns different with the different gears?

what other problems would i have changing centers or other things do i need to consider?

thanks all
