Got all the parts for the diff and installed it this past Saturday. Just waiting on my axles and driveshaft now.

Whats that steeda brace? I keep breaking the passanger side front diff bolt.

Steeda brace is the gray piece you see. Helps support the front of the diff.

Update:

My axles and driveshaft are on their way back to me. No major damage reported by DSS. Axles were freshened up. Driveshaft was checked, scratch polished up and balance checked good. Should get them this week. $300 total.

Got everything back yesterday. Hoping to install this weekend.

I'm not that patient lol

Also changed the diff fluid while everything was out.

Outstanding job! Will you need to get an alignment since the subframe was out of the car?

just one example. There are at least 3 companies offering this. I'm talking about the top left/right item. It reduces the 16mm hole in the Ford bushing to 14mm to match the dia of the bolt. It's a mind-blowing catastrophic error by Ford engineering which apparently they can't be arsed to fix in 5 years. I wonder if the GT500 got a correctly designed part.

Who else makes something like this? I really only need the bushings tbh.

That’s for the subframe, need the rear diff bolt bushings, 16mm OD, 14mm ID

since you're local I'll make some on the lathe and you can come pick them up.
I also bought some Delrin and reamers to make the IRS alignment bushings as well.

Oh shit that's rad! I'm actually in Tidewater, but I can get one of my buddies up in Nova to grab them for me, otherwise I can probably send you a prepaid envelope to drop them in the mail.

I have the subframe alignment bushings already (IDK why Ford needs 1/2" of slop to install that rear cradle lol)

LMK what I owe you man, thanks!
