Build update, need some reference pics

[Pat D]

So the '74 is coming along nicely, all the wiring is buttoned up and the headlamp and gauges are installed, everything is working well. New front and rear sprockets are on, right side cover is polished and back on, chain should be waiting at home today so the left side cover will be going on as well. Clutch actuator(worm) has been cleaned and lubed. Side covers have first coat of paint, waiting for cure before wet sanding.

Here is what I need some help on- at some point the factory seat mounting system was modified/damaged. I have a single hinge tube on the right side of the frame for the rear hinge, I need to add the forward hinge tube. There are 2 hinge tubes sloppily welded to the left side of the frame, for what purpose I have no idea. I do not have a helmet lock or a seat hold down latch.

If anyone with a stock mid 70's bike could take some pics of the seat hinges and hold down latch, as well as the under side of the seat pan, it would be very helpful toward getting this thing back to, if not stock configuration, at least functional. I have a good seat and pan, but much of the mounting hardware is missing from the bottom of the pan, so I can't use the seat as a jig to locate the hinge tubes.

Here's a few pics of the current state of the bike. Thanks in advance for any help on this seat issue!

Chain arrived today, so front sprocket is torqued down, chain installed, chain guard installed, and left side cover is on. I gotta get busy on the tank!
