Where to buy repair kit for split/tear in leather seat

[gsxr]

Hi folks,

I have a 5-6 inch tear in the driver's seat bottom, as seen in the photos below (1995 E420). Yes, I know the proper fix is to replace the leather panel, or replace the entire lower seat cover. But I'm not interested in spending that kind of $$$ right now ($250 minimum, and that's if I take the seat out of the car and diassemble it myself). The local upholstery shop recommended by the MB dealer looked at it and said they couldn't (more probably, didn't want to) patch it, and they would have to replace the perforated panel.

Since the tear is large enough to get my whole hand in underneath, I'm interested in some type of repair where you slide a piece of material underneath, that is glued to the back side of the leather. After much searching online (and on forums), all I can find are cosmetic repair kits - i.e., kits that fix worn areas, color or fading problems, holes, etc. All surface fixes, nothing at all like the problem I have. I can't find a blasted thing to just stick on the back side of this split and glue it back together! Anyone have a link to a kit, or DIY procedure, etc? I really hope it doesn't come to sticking duct tape over the top....


Thanks!
