New old stock, fresh out of the 1970's and nice. I am not sure what brand these are or what all models they will fit. No names or marking brands on them. 11-5/8" center of mounting hole to center of mounting hole. Mount holes are for a 3/8" bolt or stud. They have 3 adjustments on them for cushioning. They have some minor shelf wear and signs of age. They are new old stock 1970's. Any questions please ask. I ship worldwide.
