Having some trouble with aligning the right boot cowl during the boot cowl build. I have good spacing at the top diagonal, flush with the firewall angles, but the right side is 3/16" shy of where it should lay on the door pillar and fabric spacer. The right boot cowl starts flush at the top of the door opening with the pillar, but then doesn't follow the angle, getting further away from the pillar edge, and not reaching my drawn 1/2" line on the fabric spacer. If I pull the boot cowl back to where it should be on the fabric spacer then it is not flush with the firewall angles. I've started over twice, the firewall has good contact with the fuselage mounts, nothing holding it out. What can I try? The left boot cowl fits proper, easily meets the 1/2" line drawn on its fabric spacer. Thanks.
