These Dimensions are from a 00 Cat skid that was put in a 04 Viper S
First thing I did was get my rear mounting location by measuring back from the center of the drive axle, and used the Yamaha rear outside mounting plate(that fancy washer on the rear mount bolt) as a template for the hieght( this actually gives you more clearence to the top of the tunnel than in the cat - the tipped tunnel). This gives you a center line(check the drawing) to measure from for the front mount location. This setup gave me the same ride hight as the pro-action but the same aproach angel and geometry as the Cat.
I did have to remove about a 1/4" off each side of the front mounts, but the rear of the tunnel flexxed enough to install the skid. You will have to make mounting plates and bolt or rivet them in for the front mounts.(See 2nd pic)
The only concern that I have, is that the pro-action tunnel is not tipped in the rear as the cat tunnels, so far (about a 1000 hardcore miles) I havent had any issues. There are no track rub marks on my tunnel, but I am not studded. If you are studded, be sure that you have proper tunnel protection.
I do not guarentee this setup, but I will say,so far so good for me!
