Neutral switch in 904

Are you sure they are just failing and not being pushed to hard from being in to far ? the replacement made by Standard which I believe is the only switch available is too long internally . I had to space mine back almost 1/8 of an inch with washers to get my reverse lights to function and I would bet being too long that way probably slams the switch back into the back of the housing . The one I replaced was cracked three ways in the ceramic on the connector end , bad enough to seep fluid actually which is what led to me replacing it and getting a bug up my backside about finally getting those lights to work .
