Looking to replace qty 4ea or more Insulated Glow Plug Cap/Cover(Pic attached)Not a big ticket item over in England/Aust. like $6.00 U.S. but the shipping will kill you in USA! Have only located them in England at Rough Trax under the part #ELECO21-do not have a official Toyota part#? Maybe some other Toyota diesels use the same for Insulating/Earth grounding? Any help appreciated if available in the states??/ Cranky e-mail dhdslimbow@yahoo.com
