Thanks guys.
Yah, the lexan is just to keep some dirt away from the shocks. It was like a $1 or $2, so I though I might as well get them.
Sylvester - I put 3 screws going from underneath the chassis into the spacer using existing holes in the chassis. Then I put 3 holes in the actual battery tray that came down through the tray and spacer. I tested earlier to make sure the hole was the right size so the screw would be tight. So in all there were 6 screws used. Let me know if you didn't understand it. I can try to explain better. I am hoping it will hold, but I won't know until I test it... The screws included were also the exact length needed. The plastic spacer is also pretty dense, so I think it will hold pretty tight to the chassis and battery tray.
