Pics of the unidentified front drive path idler pulleys:

The purpose of these pulleys appears to be to guide the drive belt straight onto the rear drive guide pulleys (those rear pulleys being found in all Evo3 IPBs, GT1009). The plate on which these front two pulleys are mounted is separated from the frame by about 1cm, and is welded on. The heads of the bolts that mount the pulleys are between the plate and the frame, and as described before have ROUND HEADS (determined by feeling in through the access slots in the side of the mount plate) so I can't slide a flat spanner in to lock them for undoing. WTF??
The IPBs and owner's manual diagrams of the drive belt path show only the rear pulleys, and it is possible that bypassing these front pulleys would have the belts approaching the rear pulleys at about 12 degrees out of alignment - see the belt path diagrams:
Mostly I'm seeking confirmation that taking out removing the front pulleys and having the drive belts go straight to the rear pullys is likely to work, even with the 12deg approach angle of the drive belt to the rear pulleys.
