Completed riveting the corners and upper cross beam of the firewall. Used the angled shim to get the corner rivets by the motor mount brackets, and it worked really well. Clamped the upper firewall in place and drilled it to the lower firewall. Installed the seat belts except for the center two - with doing the lowered seat mod, the bolt provided (AN5-13A) is not correct. Need to order 2 of AN5-6A and one of the matching nut. The hardware kit has a bag of washers, so there are extras there. Alternatively, maybe order an AN5-xA where X is about 2 1/4" to have one bolt going across both seat belt brackets like the original configuation. Can't put the seatbelts up the exact center anymore because the pushrod goes there. Rolled the seatbelts up and put them in plastic bags to keep the dust off.
