Diff replacement critical dimensions?

Post by n2xlr8n » Thu Aug 04, 2016 7:43 am

Howdy fellas!

I'm replacing the notoriously weak 7.5" rear in my 1990 Ranger with a 8.8.

If I'm using the 7.5 as a pattern (but not necessarily the brakes), what are the critical dimensions I must provide to the fabricator?

There used to be a build-up sheet somewhere online (and saved on a long gone PC :cry: ), but I can't find it.

Any help?

Found it on Strange's website, but feel free to comment....

It's tough to find someone local that knows how to do this properly, so working in a shop full of fabricators, we're going to do it ourselves.

Another Q:

I've seen my buddy (retired/not interested) use a inconel bar to keep the tubes square during his TIG process.

1) Can we wire weld it, and

2) Does the bar need to precisely fit into the housing ends?
