Over here the Granada/Scorpio has more of a dip in the middle.
It's a touch wider but will work with stock lower arms.

XR4Tis have 26mm front bars and the Scorpio is 27mm so a bit of an upgrade as well.

When I did my V8 I used a T5 and had no ARB clearance issues, I assume your bellhousing must be bigger?

It's a Tremec bellhousing, probably for the TK0 600 that I've butchered to fit the T56.

I'll keep an eye out for the Scopio ARB if it has a bigger dip

Hi Mark, I've got a couple of spare Granada Cosworth front ARB's, if you want one drop me a message.

I'll go down to my lockup at the weekend Mark and take pics of all of the ARB's (I think that I have 6 and at least 3 are different) so hopefully one of them will be suitable for your needs.

re the cossie granada front arbs

they should be 29.3mm thick and when you lay them op top of a normal sierra 2wd arb they should have the same angles on the threaded bit that the outer tca bush goes through

if they are of a different angle then they will more than likely be the 4wd arb's

i went through a lot of testing back in the bay and the granny bars made the turn spot on but the straight ahead a bit vauge and dead when coupled with the 4wd versions so bare that in mind if you are thinking of changing anything else in the front as to what effects it will have on the geometry

At the moment it's all Sapphire Cosworth 2WD, It would be nice if the Granada ARB had the same geometry but had a bigger kink to miss the bellhousing

Diff is a 3.54:1 XJS Power Lok

I know there is no chance of hitting max revs in top, but it will make a nice overdrive

Before ford motorsport campaigned the sierra Cosworth RED rallied the early sierra's, they quickly realised the 7.5" unit was crap and used the 4HA into the sierra beam.

I had a complete RED back end on my 3dr years ago after expiring many 7.5" diff, bloody heavy but bomb proof and a great LSD.

I have loads of pics somewhere of it fitted to the beam, this was like well over 15 years ago I had it.

The RED cars used them in the early 80s.

The Granada roll bar pushes the TCA's forward, so you need to move the lip further back on the roll bar where the big washers fit over the bar to get it back into the Sierra position.

If that makes any sense?

Makes perfect sense

Any idea how much metal needs removing to get the caster angle right?

Thanks for the kind offer

Does anyone know 100% if the Granada one has more clearance near the bellhousing?

Think it's about 5mm?

You need to ask Damocos with the silver Saff BOB turbo.

He's done it that's how i know.

OK, thanks mate.

I need to gain way more than 5mm so will stick with the Cossie ARB and chop a bit out of the bellhousing!

No, sorry, its 5mm you need to machine back on the ends (not the very ends) of the roll bar to move the cups/washers 5mm back and ultimately the TCA's.

Ask Damo with the BOB turbo Saff.

Not the clearence under the bell housing that you are after - I have no idea if they are different in that respect.

Yep. The jag flange is cut off and a new round flange welded on to keep std shafts.
Did 480ft/lb starts on 10"wide slicks no worries.

Finish is getting quite good now, I had bought a brand new gravity fed gun for doing the top coat but can't get on with it.

Used my old knackered primer gun and got better results

Regarding the arbs I machined 25mm off mine a run the thread right to the end and fitted a slim nut at the end (like track rod locking nuts) so that you can adjust the front end fully(with adj TCA's)

Have you looked into machining the bell house for the clearance or is to severe

I won't be able to tell on bellhousing clearance until I've bought a flywheel and had a good look, if there's enough room I'll chop it away to clear the ARB.

Nice idea on the adjustable caster angle!

The shell is looking awesome!! Just for information, the Granada ARB is the same as the sierra one, apart from that it is slightly wider to accomodate the longer tcas. The angle to clear the gearbox is exactly the same and so is the length for the caster angle.
