I'm restoring a wrecked Pterodactyl Ascender which had the hang tubes broken off at the junction with the front cross-through, but I forgot to take an important measurement before cutting off the damaged tubing...

Can anyone with a Pterodactyl give me an accurate measurement of the center-to-center distance between the rear cross-through and the front cross-through of the hang cage please? It doesn't seem to be in the manual anywhere.

Thanks a lot!
