Updates !

Back home at last

Wasn't happy with some of the paint so sorted it myself

Rear door also had issues so took it off and had it fixed else where...

Time to raid my hoard of new old stock parts

Next was an 8 hour round trip to MK Motorsport to pick up rear beam

6 degree fully adjustable rose jointed with Jag power Lok diff, some really nice fabrication and welding gone into this - I've had this Sierra for 5 years now which has given me time to save up - Just as well

I now need to sort out drive shafts, prop shaft and make a billet diff cover...

Also finally picked up the bumpers from painter who also wanted paying for the respray

Weather was crap today, garage is full, shed is full so lounge became workshop.

Plenty still to do !

What's the thoughts behind using the jag diff ? are you going to wire lock or use thread sealer on the 4 top bolts ?

Only thing that gives me concern about the axle work is in this photo above if the quote works.

Only for the reason I seen one come loose on a friends car here allowing loss of control of the rear arm ! He was lucky he was pulling into a car park at the time.

Basically the tube nut type thing that secures the rose joint thread had no form of locking, it came undone and simply screwed out.
I drilled and tapped a small hole in the middle of the rose joint to add a simple lock that would prevent the other bit ever coming undone or certainly make it a lot harder.

It isnt knocking the fabrication or anything like it, the guys car here had a Bayjoo axle and it used same fittings, another friend had one done by Danny which also employed same fittings. But one coming undone in such an important area would make me paranoid !
More so as I'd been out in the car with him literally a few days before with him driving slightly enthusiastically...which could have ended in a huge mess if it came out then

There lock wired as standard from the factory, most of the cobra guys do it, or as I did thread" lock" , sealer was probably the wrong word !

That welding is almost too pretty to stick away under the car......

You mention making a billet cover.. what are the brackets/tabs welded to the present cover going to be for?

Using a Jag diff as it's tough and has a proper LSD - the 6 degree beam gives lots more grip, which in turn puts more load on the diff and the Cossie one is not too strong

The bracket gives the standard Sierra mounting point position, so I can take measurements from the Jag steel cover for the drawing work.

For some reason the Jag diff as standard uses tapered bolts and lock wire to hold in on. No idea why, probably just use thread lock and standard bolts.

I'll make sure the adjusters are done up good and tight if they have a habit of coming undone

Paintwork correction has been driving me crazy and taking too long, but it's getting there...

Also spent a lot of time drawing the diff cover, not sure on how I'm going to make it yet though.

I'm sure if you were very patient, you could carve it out yourself with a die grinder and some hand tools.

Very very very very patient.

Can MK or some of the other guys not CNC it ? Expensive proposition for a one off though.

Would there be a similar diff cover from another vehicle that could maybe be used as a base ?

Car's looking great.

Looks fabulous. I would be scared to drive it!!

Thanks chaps

I have a CNC at work, but as of yet have not learned any tool path software.

I like a challenge !

You drew that

How the hell do you do that?
Car is looking awesome Mark you gotta be pleased.

Using the lounge as a workshop pretty cool too although not sure that Mrs G would be happy for me to use our lounge for car stuff

Keep up the good work
