You can unbolt your solid discs and swap in a pair of vented discs. You will then need the wider calipers to go over these. The 190 LWB Mk2 had this setup from factory, so if you can find a set of those, then great. I have one of these vans, and it stops really well, even with a Supercharged V6!
Another option, is to use the CALIPERS from a Daf 400 or LDV Convoy van, on the Transit discs. Again, these had the option of solid or vented discs, and single pipe or twin pipe calipers, so you need to be careful that they match. They are a larger caliper than the Transit one, take a larger pad, and the pistons are larger at 44mm vs. 41(?) of the Transit, which gives a hydraulic advantage, but they will still clear the 14" wheels (I have tried these)
Yet another option is that a lot of Range Rovers and LandRover Discoveries had a 4 pot caliper which I believe will bolt on and clear a vented discs. (Pre 2000 models) But I have not verified that for myself.
