Doug and I whacked it in in less than 3 hours yesterday at NeedFordSpeed's house (Gilly). His Dad has every single tool and a nice 3 car garage which made life very easy.
Along with the diff we:
-Changed rear pads
-Changed rear calipers
-Changed front pads
-Found a mounting bracket for a trailing arm loose so tightened it to FT
-Put good set of trailing arms in with good bushes (Selby lower and Pedders upper)
-Tightened all trailing arms and linkages to FT
Well it goes awesome! Pulls a bit harder but I can't really tell how hard until I put some Petrol in a get the mixer out, but it's definitely pulling harder. Oh, and the minor detail....it gets very good sideways in first and then in to second :D Especially in this weather.
The rear end feels a whole lot tighter with everything absolutely tight, and the trailing arm mount fixed. About 50% of the bolts weren't tight enough. We greased and cleaned every bush and mounting thing as well. The back end feels 90% with the program now and there isn't as much noise as there used to be.
Now the problem

I got no brakes :o( We let the master cylinder run dry and the bleeding didn't do crap. The pedal has to be at the floor to get any effect at all. I've been to some mechanics today. Two of the mechanics reckon a pressure bleed will solve the problem and one thinks I'll need to d/c the lines from the master cylinder pump the fluid through, connect and then bleed all brakes again. Not fun but I think I might just pay them to do it.
Total cost:
-Diff came with Frog Racer, so almost nothing.
-Trailing arms came with Frod racer.
-Calipers with Blue EA S-Pack wreck before Frog racer.
-Pads which were 95% came with Blue EA S-Pack
-High Performance Brake Fluid $9
-Piston resetting tool for EA-ED $25. MoParts people wanted $62 for this and Repco wanted $40. Gilly did some smart talking and got the price down to $24.80 with a staff discount. Ask him what he did, it was funny shit.
So all up so far about $35.
I think we broke the record too, just under 3 hours. That was with a lot of quotes from the movie Chopper

Great movie that one eh? :D
