M10 - 1.00 x 20mm is a good answer here. The surface on the yoke is recessed, which makes fitting a socket over the bolt head a little iffy so I'd really would prefer to have a flange bolt, but I cannot find any. So, it's either a hex head straight against the diff yoke and a janky socket fitment, o...

Yeah, it was originally a Ford Motorsports aluminum driveshaft for a Fox body. The shop: 1. Reused both tube yokes (the things the u-joints attach to) 2. Replaced the tube between them with literally scrap tube* 3. Installed new u-joints at each end 4. Re-used the slip yoke that goes into the transm...

Solded!

I dunno… what someone wants to pay for it? $70? 50% off?

It's the Haulsee design, but purchased about 10 years ago from 460 Machine. It's a chunk of aluminum, but in case you care it has about 30k on it. :) In excellent shape, includes all original hardware (from the driveshaft, and into the diff flange). https://www.sacsaabs.org/sacsaabs.org/misc/xr_dsad...

There was one on "Nice Price or Crack Pipe" today... car appears to be in Michigan, $2500, looked pretty decent!

Got my customized driveshaft back from Driveline Service... the ended up just replacing the whole tube so it looks great: https://www.sacsaabs.org/sacsaabs.org/misc/xr_longds1.jpg New u-joints, new diff yoke, and ~20mm longer than it was. The PTI yoke works great: https://www.sacsaabs.org/sacsaabs.o...

He was also involved in Fiat and Yugo, and quite a few other odd things. Guy is probably maddening to work with!

Turns out this is a difficult bolt to find.

I'm dubious that one could derive octane requirements simply from compression ratio. Tendency for knock is going be driven by overall compression ratio, but you also need to factor in injector geometry, intake temps, ignition angle, and surely quench area when understanding an engine's resistance to...

Looks like it's an M10x1.0 … maybe 20mm long? The yoke and diff flange are both ~9mm thick.

Anybody happen to know the spec for the diff flange to driveshaft yoke bolts? I was using a Haulsee adapter and the allen head bolts but am going back to a conventional yoke.

I didn't end up doing this... as much as I'd like to have a Scorpio, in the end I determined I just don't need a Scorpio that needs body work. I'm sure I'll regret it someday... Instead I bought a Saab that needs body work. :D https://www.sacsaabs.org/sacsaabs.org/misc/86900base_wheels3.jpg "Bought"...

Oh, I didn't take photos but this morning I knocked the ring gear off the diff... hosed it down with penetrating oil, removed the bolts, tapped it off with a brass drift. No struggle there, no force needed... just a few minutes spent tapping in a circle til it fell off. I boxed up the adjusters / be...

It's less organized that it looks - no accounting for thread pitch or flange, etc. It's better that it could be but I still spend too much time looking for hardware. There's just too much and not enough space. I won't tell you how long it took to clear space on the bench for this operation. One wall...
