Abstract: An improved shock isolating mount is designed for securing a body part of a vehicle to a support. The shock mount comprises a two-part spool that includes: a spacer formed from an annular flange integral with a tube, the tube projecting through apertures in mating elastically resilient bodies and a mounting part of a vehicle body part disposed between them; a thimble, formed from a flange integral with a tube designed such that the thimble tube can telescope into the spacer tube. The thimble tube is formed into a polygon shape at the tube shoulder adjacent the thimble flange and the spacer tube is formed in a matching polygon shape such that the thimble tube shoulder can mate with the spacer tube. The thimble tube has an enlarged end which is engaged by a plurality of inward protrusions mounted in the spacer tube to prevent the spacer and thimble assembly from accidental disengagement.
