Modifying 200sx rear subframe?
Hi all!
I've got a Ford Anglia 105E which is having the running gear from a Nissan 200SX S13 shoehorned in! 
I've got two options for the rear axle/suspension.
I either keep the original Anglia live axle/leaf springs, or I fit the 200SX subframe.
I would probably prefer the 200SX stuff, due to independent suspension, stronger and more easily readily available diff (will be running at least
200bhp, possibly up to 300bhp!).
However - the track would need to be reduced by about 8" in order to prevent the use of a bubble arch kit (I'm trying to keep the looks of
the car completely standard, especially for the "what was THAT!?" factor )
Now if I was to use the 200SX stuff, the problem comes in what/where do I modify in order to get the required reduction in width.
Here's a picture of it for some reference 
(Click to enlarge!)
Now I would imagine I wouldn't want to mess with any of the arms/geometry bits, and just modify the bit in the centre, and the diff mountings.
However, this will mean taking ~4" from each driveshaft to get the required 8" reduction - now will this pose much of a problem? The
Anglia will be much lighter than the 200SX, so I would guess it wouldn't need as much suspension travel, therefore the risks from a potentially
sharper angle on the driveshafts wouldn't be as much of an issue?
I've got a couple of months to ponder over this - but having some kind of idea would be great!
Thanks in advance!

someone will probably clarify this but i didnt think that the SVA would allow shortened driveshafts on the grounds of safety but im not sure, i might
be wrong
And you run and you run to catch up with the sun but its sinking, Racing around to come up behind you again, the sun is the same in a relative way but
your older, shorter of breath and one day closer to death

My dad's Anglia passed an SVA in 2001 with 4 shortened driveshafts
Unless something has changed since then, of course!

I suspect it might be easier and more effective to design a custom subframe with IRS that utilises the existing diff with mofiied driveshafts. A
tubular steel frame and wishbones with coilovers would be lighter than the 200SX subframe and could be designed with better geometry to suit the
application and also specifically to fit the body of the Anglia.
A start point might be to look at the RWD Fiesta conversion on www.mkengineering.co.uk to get an idea of what others have done. Might even be worth
approcahing Martin Keenan himself to see if it's something he could help you design and fabricate.
Sounds like a cracking project by the way

Depends on what you want but I would not go with either option!
I built a RWD Peugeot 205 in 1998 among other rwd projects, and used a 5 linked capri atlas axle.
This is the common, probably most effective, and certainly pretty cheap, way of uprating the anglia back end.
Its all been done before and all the 5 link kit etc is available off the shelf from rally design, and if you want to do it yourself then the drawings
are all in the ford escort rally prep book.
The IRS is nice but as others have said, you would be better doing your own subframe, there are a number of cars about, some quite well known, with
suitable setups, you will probably have seen the cossie turbo rwd puma rally car (forget the name of its owner) and the vaious copies of it that are
around, plus the various fiestas that have been done.
Retro RWD is the way forward...........automotive fabrication, car restoration, sheetmetal work, engine conversion
retro car restoration and tuning

Worse case you'd have to buy new shafts to your design from GB engineering for £90+VAT each.
