Okay, I'm striking out finding the answer on my own. Going to do a new build install of the FlyBoys Supertracks on a slider -7 and cannot find the part number for the -8 canopy slider rail so we can have one continuous rail rather than putting on the extension. I know people on here have said they've done it, but Van's part ordering had no idea what I'm talking about and the wait on hold to ask tech was eternal today. Can anyone provide the part number or the magic words to give Van's so I can get it coming my direction? I know on the -7 it's C-762 & 763. Thanks!
