I am struggling to get my desired diff ratio in a live axle.
Has anyone done the swap to a Sierra back end.
What sortof job is it?
Thanks
Tony

one idea may be for you to go a DE DION conversion.
possibly easier.

But if you definately want to go the IRS route, then i would personaly use the HAYNES ROADSTER as guide, most of the parts, if not all, are readily available.

what car are you talking about? i am considering it

Thanks for the replies.
The De Dion looks interesting.

It's a Stuart Taylor Locoblade.

I'm swappin the Atlas rear end (four linked trailing arms and panhard rod) for the De-dion with a Watts linkage. I'm hoping to make a subframe that will pick up on the trailing arm points on the chassis but my car isn't normal!
This is as far as I've got so far!!

GavinC did this conversion at the build stage using DeDion, the main difference is the Sierra axle is longer widening the rear track.
The trailing links brackets are therefore further inboard on the DeDion if using a book chassis compared with the wider chassis used with an IRS setup.

I decided to chance my chassis from live axle to de-deon.

I originally fitted an escort width de-deon with standard front wishbones

Was struggling to find someone to shorten the driveshafts so then had another de-deon made

This was sierra width, but kept escort width at the front end.

I the decided to change the front end for sierra width.

All this before the car was IVA'd.

I would like a De dion axle but i am not much of a welder.
Is it possible to buy one already made?

will they take more power than a escort english?

Is this a design to replace the escort axel, leaving all pick ups and arms untouched? I have live axel fury and wondering is this could give me anything??
