If the 13B is 85 or older the side housings should swap. If the 13B is 86+ then the water seals will be in the side housings and the 12A water seals are in the rotor housing. This means either you will have 2 water seals meshed together, or one water seal trying to fill in 2 grooves. Either way, it won't work.
