Thanks for the input Dags, I was thinking a little that way too, I was going to stop by the shop in the morning, I have about 7 or 8 of them laying around but as always none have feature mods in them, we stoled them over the years for quick fix service calls, will see what happens, thanks for everybodys input so far
