It takes a whole lot of work to fit APC's , so I'm going to assume that the BYO's will be only slightly less effort. I also assume that you are using a plastic spinner. It can be done, but you will have to really carve the screw posts on the engine center line side. It takes removal of about a third of the post thickness, or more, to get the APC's in. Patience and a good Dremel tool is all it takes. Good luck.
