As Ray says too many differences. As far as belts go, there was a place at W'park that was like a mini warehouse with 100's of belts, V's (int,ext ) ribbed, flat. in fact I think they would make to order, for those who remove bits, or have unstandard set ups. They also sold every type of filter. Obviously all this was at a premium. I used them for some very old stationary diesel gensets, where parts are no longer generally available. That included a Volvo that I'm sure came out of a "U-Boat" after the war.
