I made my own from a piece of 1/8" aluminum , I bought the PMR cover for my Predator and used it as a guide line to make this one , truly simple , after making my template and cutting it out in one piece , I brought to my Buddy's shop and used a hand brake two make to bends , my other Buddy welded the one seam . I used a 1-1/2" piece of angle iron to make the mount for the engine , drilled bolt holes 5/16" to attach to engine , drilled to more holes on top side of angle and welded nuts on underside for attaching chain guard . I don't have all the pics but this should give you an idea !
, this is mine next to PMR before I drilled mounting holes ,
I hope this may help you ?
