Thanks to John Appleby for posting this information on the old Yahoo! Loopframe_Guzzi news group (which has now moved to Groups.io). In John's own words:
Shape of the seat pan is going to be tough to create a pan with but here are my rough measurements of the pan:
- Front to back: 21 1⁄2 inch
- Side to side at the rear frame mount: 13 1⁄2 inch
- Side to side at the front frame mount: 7 1⁄2 inch
The pan has a lip around the sides (not in front) that is about 1 inch high.
The back of the pan bends up approximately 3 inch starting at the rear seat mounts. There is a 4 inch square piece of rubber centered on the pan starting about 1 1⁄4 inch from the back of the pan to protect the rear fender.
The front frame mount is a U shaped affair that is 2 1⁄8 inch wide and 1 1⁄4 inch high with a 3⁄8 inch slot that goes down 5⁄8 inch for the tank mount bolt. The front mount is centered on the pan 2 1⁄4 inch from the front of the pan.
The rear mount is a 3 1⁄4 inch piece of steel bent up 90° at 1 inch then bent 90° forward at 1 1⁄4 inch with a bolt receiving hole 1⁄2 inch from the front of the piece and a nut welded to the bottom for the bolt to screw into. The rear mounts are welded about 13 1⁄2 inch back from the front of the pan, this can be better measured by the mount holes on your bike.
Both front and rear mounts are steel stock 1 inch wide by (approximately) 1⁄8 inch thick.
The mount holes for the chrome bar would be best measured from the piece but the bolts on mine are welded 14 1⁄8 inch back and 3 1⁄2 inch from the side of the seat pan. The rear most mounts for the chrome rail is 19 3⁄8 inch back from the front of the pan and 1 3⁄8 inch from the back of the pan. The measurements are approximately on center and the bolt is about 3⁄8 inch (with a 3⁄4 inch nut).
