I bought some Mato gears from Ebay for my HL Panzer III - the gears are fine (apart from stripped grub screw but I expected that!!) but the mounting plate that was supplied is not wide enough to use the mounting holes on my tank - it appears to be approx 5-6 mm too short.
I can line either side up with the mounting holes, but it is not possible to mount the plate centrally so that each gear is mounted equally

The Ebay seller is not playing ball at the moment and the only way I can see to use the plate is to cut it half and would then be able to mount each gearbox, albeit on separate plates - Would this be ok or would it affect the rigidity of the tank?
I have trawled the net and can not find any one who sells mounting plates.
Any help would be me much appreciated.
