A lot!!!!!
How are you Sid?.                                

Recovering from being hit by a Kenworth on the highway while working on a Peterbilt so not dead is good!

Geez, Sid, be a bit more fair to Frieghtliner and Mack and the others when you get smashed into.  Gotta be an equal opportuniy target.

Seriously - you got hurt?  I missed the note from the doctor about it.

Jon, Sid doesn't kid around when it comes to stuff like this!.
I hope you're OK man?.

I guess you could call my liner a Peter Built!!!.
Not so great right now. Figuring how to mount the rear end is another nightmare.
The side to side bit is OK but the up and down (or lack of it) is giving me a hard time.
With packaging being so tight on such a narrow track I've got a problem.

I have a pretty simple idea but it looks like it will concentrate all the vertical loads
on very small areas left and right.  I'll have to dummy the system up as best I can
and post pics.

That's funny, the way you explained your rear end pretty much sums up my right knee, it's kinda ok with going up n down but the whole leaning turning bit sucks!
What do ya get when ya have a Peterbilt, a Kenworth & a Freightliner three wide on a narrow two lane country road? A wounded Kiwi. :-P

Good to hear it wasn't worse. That's dangerous work you do.

Been working on the rear end set up.

I'm going with a similar set up to the old Speed Demon the way the diff is mounted.

My centre portion is different but the system I'm using is fairly close.

[tauruck]

The ears on the GM centre portion (i almost removed) have come in handy.

I had some doughnut type bushings machined and instead of using the sides of the
diff like SD the doughnuts are pressed in, one from each side and bolted. One on each
set is threaded.

[tauruck]

I cut and drilled the channels to suit my needs and then welded them to two of the doughnuts.
The channels will accommodate the rod ends  that fit the triangle still to be fabbed.
After bolting the channels to the doughnuts I welded everything together.

[tauruck]

Some other angles of the components.

They'll go into the fridge tonight and be ready for pressing in the AM.

[tauruck]

Few more.

[tauruck]

I heated up the diff housing and pressed in the bushings that were cooled in the freezer.
It turned out good but although the surfaces are flush against each other and one end is threaded
there's this small gap that's less than 1mm between the cast iron and the EN8 bushings.

I have some welding rod that is good for cast iron to EN8. Should I tack the parts just for safety?.

   I don't think it's necessary. There's not much shock loading on dirt or Salt like you have on pavement in drag racing. More of a slow steady load.

Thanks Doug, those inserts went in pretty tight.
I really had to put my back into cinching them.
need a few days rest now.

[tauruck]

Trying to do stuff now to save time later.
I have 8mm plates to use for mounting the 8 Bosch coils to.
I really had my heart set on completing the task today.
Problem is Bosch went with a 3mm hole on the mountings.
I little small IMO but I'm no designer so instead of reaming out the 16 holes to 4mm
I'll wait for Monday and buy the right fasteners if I can find the right stuff.

[tauruck]

My top triangle fitting on top of the diff looks like a no go.
The two fittings are so close I see no benefit.
I'll have to use the outer plates as the Speed Demon guys did.

I was over at Karcher to collect my sponsored goods today.
High pressure cleaner and industrial vacuum cleaner.
Many thanks to Dean Fairley and staff.
