I installed the bracket I made for the landing lights. I wrapped the nosegear with thin rubber and use a "U" bolt from a 1 5/8" muffler bracket. Then I installed the halogen lights from Harbor Freight.
Based on information on the RotaryWings website, I replaced the water themostat with one that had a relief valve
The O2 sensor I received in the kit had threads that we almost completely destroyed. I purchase another from Checker Auto and installed it on the header along with the temp probes.
