Chuck,
Yes they are available, but very expensive. If you what to go down that route I would suggest you buy a "wrecked" mercedes which has ABS then canibalise it for parts.
THis is the route I am going down for the 1974 BMW 3.0Csi I am restoring, I have bought a 1986 BMW M535i where I can mix and match parts as required. ABS 5 speed gearbox, more modern fuel injection etc etc (Whole car cost me £600
)
99% of drivers follow too close to the car in front as they can't judge distances properly. I know because I do it too. However with modern traffic if you leave enough space four cars dive into the gap you leave!!
My final comment when driving an older car you have to drive it in an "older" manner I do this in my 1962 MGA which has great brakes but rather primitive handling. Same for my 2002tii etc etc
I think, and I am not being rude here, that people have become so "cocooned" by modern saftey equipment (Nothing wrong with the equipment) that they have forgotten the basics of driving. I think that's why here if there is a crash its usually a bad one as people drive well beyond thier capabilities and when they drive "beyond" the abilities of ABS traction control etc etc they don't know how to cope with a skidding car, look for escape routes (gates, junctions, wide grass verges)
