New Bfs Reel + Upgraded with ported spool, handle and tension knob. 

I recently bought this SeekBass et101 bfs reel off of AliExpress, it's the same as a seasir cast x and having a seasir mansory on hand I thought I'd see if thr short shaft ported spool from the mansory would fit, which it does. so does the handle and tension knob. so it's the same frame. the only thing needed is the tension pinion located under the mansory tension knob and that fits under the cast x/et101 tension knob. Likewise the long shaft spools fit inside the mansory with no extra parts needed, you don't need to use the tension pinion as the longer shaft is what the tension knob will tighten against. happy fishing.
