SIG GLASS FILLED ENGINE MOUNTS
Molded from a new, high-tech, glass-filled plastic, and braced with webs, these mounts are far stronger than typical glass-filled nylon types. 
The real beauty of these mounts is that they don't require tapping.
Simply drill holes to clear your engine mounting bolts, then fasten your engine to the mounts using 3/4 in. long bolts and aircraft
lock nuts (4-40 or 6-32 depending on engine, not included). Bolts and blind nuts are included for bolting the mounts to your firewall.
