I too am interested in the dimensions of the 3 litre rebound rubber C5964. On my car the wishbones have always applied slight pressure on the rebound rubbers. During some front suspension work, I bought new ones (C5964) from Chris Prince mainly to be able to compare new v. old (but probably not original) dimensions. The new items are very good quality, with identical dimensions to the old ones. But it did not resolve the question why the wishbone has contact to the rubber. During the suspension work I found aluminium spacer-rings approx. 5/8" high fitted under the springs. This would increase the tension and raise the wishbones very slightly. Chris Prince said he had found a few cars with spring-spacers, and he showed me some from cars he had dismantled. Perhaps it was a works option for stiffer front springing. The spacer-rings are not `home-made´ but are properly designed (castings?) with recesses to accomodate the heads of the lower shock absorber studs in the lower wishbone. I could not see a reference to spring spacers in a TD21 (S1) parts book, perhaps they are mentioned in a TE or TF parts list? It would be a logical step to use slightly lower rebound rubbers (e.g. C10427?) in case spring-spacers are fitted, but I have not had the courage to try cutting the rebound buffers down, after seeing how much the rebound rubbers are compressed when the cars's weight is taken off the front suspension. So any further documentation about use of spring spacers (an option, on which models, which rebound rubber?) and the dimensions of cut-down rebound rubbers (C10427?) would be welcomed.
