IRS Differential Output Flange Height

[croweater]

I am setting out my build here in Perth Western Australia and Sierra diff centres are non existent. I am using a Subaru unit and despite it having a long nose, these are reasonably easy to get here.

What I would like to know, is what is the centre line height of the output shaft drive flanges, so that I can get the suspension and drive line angles correct.

I would like the dimension from the bottom of the chassis rail please.

It is not mentioned in the book, nor is there a rear view which shows this dimension and the axle rake.

I thank you for your assistance

For your application it would be easier to mock up the rear by attaching the rear wishbones and uprights then using a piece of steel tube in the place of the shocks set the bottom wishbone level, then run the drive shafts level to the diff, this sets diff output centre line, you should run the diff input flange level but it can be off centre left to right, Sierra diff is off centre left, right by quite a bit, the diff may even be ok nose slightly up.
Prop shafts don't run straight but usually slightly off line apparently this is easier on the uj's
