Vic, I will look for photo's of my 39, it did the same thing, Don P and I placed fan back in position in the rubber, then we drilled three holes and used 1/4" bolts/locks/nuts and bolted it in place. It works great, never a problem, original was held by vulcanized rubber and friction. Now it is centered by the old rubber and held with bolts, look at the thread on my LZ, Bruce
