Hi all, I just picked up the precision ski kit for my 1997 formula 500, and have some installation questions. First, a new rubber stopper came with the kit. It is not the same as what is currently on the ski leg. I did ensure that the kit was the correct conversion kit for this year and model. Can I use the existing ski leg assembaly? also, the kit came with three different size bushings. I think that I need to use the biggest one, but is this correct? and lastly, a metal spacer bar (cylinder really) came with the kit. I am assuming that this is not needed for installation on a 97 machine, since the ski leg on my sled seems to have a built in spaces on the skileg itself? any and all help is greatly appreciated. Thanks.
