Holley 26-57 Dashpot and Solenoid Bracket Mounting LocknutWell this item deserves a GREAT REVIEW!!! There are other negative reviews about this item that don't have anything to do with this items quality at all, PLEASE FORGIVE THEM.I purchased this item because the JUNK steel stamped nut that came with the electric A/C solenoid I bought keep's working it's way loose. Lucky for me I found this Holley nut made of solid brass that really rocks!!! it's very heavy duty to say the least and has not came loose since.I would recommend this item to anyone :-DRagenRat
