Hello everyone so I ordered 10 42 inch .063 404 pitch chainsaw chains 5 that rip and 5 that are full chisel.Problem is the 5 ripping chains have 123 drive links instead of the 125 the rest have and its to late to send them back. Does anyone got any advice as far as adding links or maybe shorten the bar possibly. One more thing is it very hard to modify one of the full chisel chains to a ripping chain.Im up for anything THANKS.
