Drakman Posted January 5, 2023 Share Posted January 5, 2023 Hi Ralph,What year is your car? 75526AW sounds like it might be close for the fronts. 75531A might be the rear, assuming your car is De Dion rear and post 2003. If you want to part with your current M1 spec shocks and springs i am looking for a set. CheersDave Link to comment Share on other sites More sharing options...
Ralph Posted January 6, 2023 Author Share Posted January 6, 2023 Thanks DavePart numbers always help,at least I know how much its going to cost me now.Not sure if you would be interested in this set of M1 shocks & springs as they will come from my 2013 SV which was used on the track, I guess the springs may be ok but not sure about the shocks. Also I probably won't be changing until late spring sometime.Thanks againRalph Link to comment Share on other sites More sharing options...

Tony P Posted January 6, 2023 Share Posted January 6, 2023 Hello Ralph. That "missing bodywork" is just a cover plate for that triangular box, into which the inertia reel seatbelts would be mounted. Unless you have an uncovered slot in the bulkhead behind the seats (which might let in road dirt - but gaffer tape could seal that up!), the cover not exactly essential - you just have two more awkward corners to keep clean.Yes, fairly easy to make if they cannot be supplied by Caterham. If you fit them with riv-nuts, you'd have a couple of secret hidey-holes! :-) Link to comment Share on other sites More sharing options...
Ralph Posted January 7, 2023 Author Share Posted January 7, 2023 Thanks Tony Think I will just make a couple of plates up i can get a sheet of ally for about £9 which will i suspect be cheaper that buying direct from caterham. I did't know what they were for until now.ralph Link to comment Share on other sites More sharing options...
