"Filler"- - - - -"Filter"- - - - -the last time I looked in the dictionary, those were different words. I believe the OP is trying to put the 216 road draft tube in the 261 block, and is having a problem with the attaching bracket. IIRC, the 216/splasher 235 oil filler cap was incorporated into the top of the road draft tube, wasn't it?
Just fabricate a different clamp to hold the road draft tube in- - - -it should work just fine!
