This should have been a simple task but there was no hole in fire wall to access bolt hole in engine mount. This was in plans but Vans did not drill hole before mounting firewall. Marked location, removed engine mount, drilled hole in fire wall, remounted engine mount and installed gear. Due to the mount angle on the engine mount and fire wall the bolt was difficult to install..
Need to seal hole with 1" stainless hole plug and fill with fire wall sealant.
