I've just arranged a rear LC 80 centre with air Locker. Will this fit in the 105? I see the ARB part no's are different

My 105 has ABS - I'd need to do a lot more than just swap housings wouldn't I?? ABS sensors, calipers etc.....

Centres are different (crownwheel is thicker / heavier), but an 80 centre will bolt in the 100 housing I believe. But then the 100 axles won't go in the 80 side gears...

Its a bit of work either way you go. Get the right locker

The price is too good to pass up - I'll put it in the middy if it won't fit the 105

It wont fit your 105. Not only are the crown wheels different but the spline count on the 105 rear axles is 31 instead of 30 in the 80.

I think you will find the ratio is different as well. I know 100 are 4.3, not sure if they all are though.
