i already viewed the rules on NHRA website and all the information states is that, lexan should have the minimum thickness of 1/8 inch and that all it says but how far apart should the mounting screws be? 3 inch or 6inch let me know im mounting lexan today TIA -ron

 

not sure if there is a spec on this.......

 

I dont think so either.......the closer the better though so wind does not get caught

 

when pop riviting it in make sure to go every 2" or so. when its hot out they will want to swell and if they are not rivited down very well the rivits will come flying off.

 

You need more on the leading edge than the trailing edge
