Thanks guys!
I think the nascar centers match the vibe of the buggy pretty well.
Aluminum would have given me a better factor reguarding the unsprung weight aspect, but at about 3 times the price.
I'm on an oldmans budget, being retired, so am committed to building as cheaply as possible...without sacrificing the vision I have for it in my head.

You're right, caliper has to fit too.
Actually, those pics are somewhat unnecessary at this point...just took them for grins.
Rear brakes will be mounted inboard with the differential...for unsprung weight considerations.
I'm building the rear end first...want to get the engine running & need everything in place for that.
Can then be tuning & taking care of any engine issues while building the front.
Something along these lines...

Jigging up for building the spindle & hub assembly.
Get my dimensions good for adequate clearance between the ball joints & outer diameter of the wheel.

Everything is level on all of the tangents.
Dimensions gained here will also show me how high to build the upper rail above the lower on the frame.

Driveline parts. Diff is a limited slip unit.
In the process of breaking it down...get rid of the un-needed housings & cast parts.

Made some progress.
Spun the axle end bolts off with the impact & got the axles pulled from the hubs.
Put the cumbersome iron locating castings on the press & pushed the hub out.
Bearings & CV's all feel real good & snug.

Now I have parts to work with. :cheers2:

What is that limited slip differential and what is the make and model? That thing going to handle pretty well with an LSD.

Also, how do you know it's an LSD? I don't see any clutch packs ? Or a preload spring?

The parts are from an 05 Subaru Legacy purchased from a reputable salvage yard.
They provided me with a complete print out including VIN, which indicated LSD.
I bought based on the printout & didn't look inside the housing before purchase & like you, I haven't seen any clutches or springs...perhaps Subaru's got a new twist on the concept...we'll see...

This chunk of billet is a good size for cutting a radius in the design.

Sockets simulate tubular tapered bore bosses for the ball joint studs.
They will be welded to the back plate & boxed in on the sides.

I did some more research & found that Subaru has a lsd that looks like a standard open dif.
Difference is, the plate that the ring gear bolts to is split & the clutches are between the two halves for the lsd feature.
This should be the unit that I have.

Clutches won't be visible until the unit is out of the case & ring gear removed.

A bit of progress.
A nice snug slip fit...have to wiggle them to get them to seat on the hub flange.

Drilled & bolted. Now need bosses for ball joints & get them fitted, before I trim out the corners of the plates. Make everything come together smooove. :cheers2:

I need to buy a tapered endmill for cutting my ball joint bosses.
Trying to determine what degree of taper I should get.
Found this calculator on line & based on my measurements that I plugged in, I should need basically a 9 deg taper.??

If any of you guys are engineers or into higher math, could you verify that I'm reading the results correctly?

And, many thanks for any feedback.

Here's the link, if anyone's interested.
