BC-1300 seat measurments needed


I think I have the original seat base with my BC-1300, but I don't know for sure. If anyone has a seat that they know is an original that they can measure, I would really appreciate it. If you have a complete seat, I would also love to have all the dimensions for the seat, total length, rear width at base and top, front width at base and top, rear thickness, front thickness, thickness at the end of the pleats, and the distance from the front of the seat to the end of the pleating. Also, I believe there is a slight rake forward at the rear of the seat. If you could measure the rake too, that would be a big help.

I know this is a lot to ask, but it would be a great help to me.
