G'day all, The HK36 stainless steel firewall is a metal sandwich construction with a fireproof fabric material in between.
I am almost sure the H36 is something similar. Last year when I replaced the throttle cable, I pulled the old one out and some fabric type stuff pulled out with it. The new cable very hard to feed through as it seemed like it was going through two holes close together. Does anyone know for sure how the H36 firewall is constructed? This info will be needed in order to comply with the new Australian AD 687 on engine fireproofing. regards Rob Rob Thompson 0429 493 828
