Tubing size on Schwinn Landmark

Speaking of mounting techniques...does anyone know the size of the down tube and the seat tube for a Schwinn Landmark? I just bought two of them and ran into the oversized tubing issue on my very first build. I think the engine mount designed by Creative Engineering is the way to go but I need the tube sizes and I don't have anything at home to do that with any accuracy.

Thanks much for the assistance.

Wow, thanks for the reply and information.

Since I posted that question I did measure the diameters myself and had my wife verify.

Downtube - 1.511
Seatpost - 1.19

I ordered two motor mounts from a shop in Tampa that does this type of work almost four weeks ago. No delivery yet and they won't return phone calls. Oh well, $75 bucks down the drain. I wanted the motor mounts they manufacture. They simply appear to be logically the wisest choice. I think I'll have to go with an alternative mount now.

Thanks again.
