as the topic says. looking mainly for 64-67 elcos but anything and everything will help

i think that the nhra rulebuook has the insturctions on where you need to mount your rollcage I know there are some rules regarding specific placment of the bars on the frame and they have some diagrams on that stuff you can look on the internet and find the info if you do a search on stuff like roll bar specs and roll bar installation and include the nhra thing in there to and you will find it.

thanks
