Just a side comment on race harnesses
.
If you use your cobra ( or other car) in any CAMS supported events check with them regarding compliance in Australia. The US belts ( FIA approved) only have a two year use by date, in Australia local belts have usually a five year expiry. Gets expensive if you have to replace them even if they look brand new
The only exception with FIA belts after 2 years with CAMS is if your enter your car in non race events ( ie regularity, gymkhana etc) and your car IS road registered.
I have spent considerable time in scrutineering with this problem
