Anyways: rear ARB is a nice idea ..
1030/1031 inner parts will fit in, but not bolt-on. It's a tight fit, you have to grind the crown wheel bolts and there's still some rubbing between the bolts and the casing, but it works. If casing would be grinded too it would fit even better.
I think that very large scale mods, like IRS and such, aren't something which can be manufactured for a sensible price with such low production numbers. I think that energy and attention should be put more on the parts, which are yet effective, but still maintain a reasonable "bang for buck" ratio.
Of course IRS and such are very nice, but setup like that isn't so hard to build by your self either, if someone really wants one. Full bolt-on kit wouldn't be very easy to manufacture, so it's pretty much same to do the whole job yourself.
Of course if these bigger mod-kits wouldn't affect on the availability of the other parts, then I don't mind..

But I think that even Dai hasn't got endless resources.
Rear ARB would be definately good, though there are shops around which make such an ARB as you want for a low price, but there's always the hassle to take the car in etc... so 300-series spesific would be good. Even better if the solution, where welding of the rear axle wouldn't be required, would be possible, because in here, welding of the rear axle isn't allowed if you wan't your car to be road legal.
If rear ARB is added, also a WATT-link would be quite good also, especially on high power appilications. Maybe a similiar DIY-kit, which are available for 200-series, would be possible for 300-series also. A kit where all the parts come with in, but the adjustments and the setup would be done by yourself.
And then one thing which comes in to my mind are the engine mounts on the Volvo engine models. As there are many 360s on the road, where engine hangs way too low because of the worn hydraulic mounts, and Volvo doesn't supply those anymore. Early Volvo engine models came with a rubber-metal type mounts (not sandwich mounts though) so maybe something similiar would be possible? I think that early mounts featured a metal casing which had rubber inside (quite like the newer type hydraulic mount, but instead of hydraulic fluid, there was rubber) so even if the rubber would've gone bad, the engine wouldn't have dropped on the road, like it would happen with a normal sandwhich type mount if it would be used in a setup, where engine is hanged on the mounts. Here's my illustration of the older type mount, it's not accurate I think, but I think the structure was something like that. (Normal sandwhich type mount on the left and early 300-series one on the right)
http://koti.mbnet.fi/mtn/images/autot/v ... ntings.JPG red parts are metal and black parts are rubber.
Though the stock early rubber mount setup of the Volvo also included a shock absorber between the front beam and the engine, so I don't know if something like that would be required with other mounts, than hydraulic ones, when the engine is hanging on the mounts.
Of course the best solution would be conversion kit for 240-type setup, where engine is sitting on the mounts, but this might be again a too big package?
So far better clutches for Volvo engine models are available from other makes and models as bolt-on (Bigger Volvos if central part is switched and straight bolt-on can be found from Opel (Vauxhall)/VW sector), so those are not needed so badly, but I don't know what's the situation with 1.4 and 1.7 models.
I'll write more if something comes to mind..

Cheers.
