rollcage specs needed

[Heath]

I'm looking at doing my cage myself with my boil maker friend, i can buy chrome moly tubing. What size does it need to be 2" 50mm with 65 thou (1.6mm) wall or 2" with 83thou (2mm wall).   thanks Heath does Cams or FIA have specs somewhere? --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.ozdat.com/ozdatonline/index.htm http://www.ozdat.com/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
