Hi there.
My little racing car uses a 1000 Ute diff currently with a 4.375:1 ratio, but I'd like to try a 4.111 some time. Are they difficult to find?
FWIW an old photo of the rear end here. It's been braced up a bit more since then and in this latest rebuild I'm making it stiffer again.

Thanks for that. Does anyone here have a set they can part with?
And how about a 3.9:1 ratio? There's a small chance I might need one of those as well.

Are you stretching the alloy housing ?
I hurt a few in my old racer
If you go to a cast iron pumpkin from a 1200 its a bit stronger
Then 3.9 is easy to get

The alloy centres seem to be fine, I guess thanks to the car being a lot lighter than the road car. Ta for the info on the ratios. Where's a good place to find them for sale?
