Warning: If you have the Steel Bungee, install it prior to installing the engine mount.
Hung the engine mount...no real mystery here, used AN6-7A bolts on the 4 points and AN4-6A on the two uppers. Lots of clamping and holding. I clamped the upper three points after making sure it was centered on the firewall and then used a hole finder (strap duplicator) to transfer the bottom two holes to the mount because you cannot clamp the lower points. After drilling those up to 3/8" I put bolts in with castle nuts so I could tighten them. Then I backdrilled the upper 3 points. Obviously 2 bolts at the top point.
Leave the board on the engine mount through the entire process.
