1 x 4204, 5-piece kit. This is the very important safety strap kit for the steering rack mount on a Jaguar XK140 or XK150 under the pinion assembly. This limits the rubber mount twist and also essentially prevents the rack pinion body  flying up and striking fan components etc. upon failure of said mount (a common age related failure problem). This bolts across both of  the 4200 steel mount plates (through step in chassis mount ) and screws into the body under the pinion side of the rack body. If the rubber fails the plates can bounce around a few mm but cannot actually break free. These bolts should always be secured with locking wire!

NOTE : Remember to shim the rack mounts properly to the chassis for optimum steering too, SEE : 4206 Shim KIt
