I just got my block heater in the mail and there is no adapter piece that screws into the block before the actual element part. So before I brave the task of removing the old plug I need to know if the block heater will fit. Anybody know about this? I am going to contact the seller(Ebay) and ask him whats up with this too. I have been waiting several weeks for this shipment and the weather is not getting any warmer. aw heck. thanks a bunch zachariah
