not for me, sadly- I have an allparts bridge
I've been thinking about it and I can't live with the bodge, The bridge pickup is about three mm longer, with differently placed lugs, to allow for the wider string gap at the bridge. Early mex jazz basses used a bridge pickup in both locations and its totally obvious that the neck pickup poles don't align with the strings,.
Having tried the bridge cover, the cavity is too small but I think a decent woodworker could widen and length it slightly. It wont look perfect, but better than a mis aligned neck pickup.
regarding the seller, he DOES state the size. However he doesn't state that this is neck pup sized and as a seller myself, I'd be adding a caution note to the listing to avoid unhappy customers. He did offer to sell me two neck pups ....hmm
