Slide out motor replacement

I just had to replace the dinning room slide motor on my Jayco last week. I used waltsrvsurplus@aol.com Sent them pics by phone and some numbers. the numbers were not sufficient, but the pics and a couple measurements got me a surplus motor at about 1/6th of a new one. I installed, using normal hand tools (and several times slithering under and out from under the RV) in about two hours, having never done it before. The only time I had to improvise, was the new motor was larger in diameter than the old one, which meant I had to find a shorter bolt and smaller nut with no washer, to allow passage. I drilled a hole in the nut and added a wire (like aircraft safety wire) through the nut as a lock. If you're handy, you can do it. hth, david
