Licensed to kill Posted November 5, 2021 Share Posted November 5, 2021 As the title says, I'm adding an air cleaner to the driver side of my B61. I have the bracket made as well as the backing plate but am puzzled about that plate. All of the mounting holes through the bracket and pipe surround are 3/8" (on the factory stock pass side) but the bolts that hold those things on are 5/16". This means that the head of this bolts are a bit smallish for the holes that they cover. I have yet to weld the nuts on the backing plate and am pondering whether to stay with the 5/16 through 3/8 holes or just go 3/8 bolts for a better fit. If I go 3/8 that will mean that I have to cut all the nuts off the pass side backing plate and replace them with 3/8 also. What have others done when adding the driver side can??. Also, anything else I should be considering that may not be obvious??. Quote Link to comment Share on other sites More sharing options...
